The first general textbook to offer a complete overview of metamaterial theory and its microwave applications Metamaterials with Negative Parameters represents the only unified treatment of metamaterials available in one convenient book. Devoted mainly to metamaterials that can be characterized by a negative effective permittivity and/or permeability, the book includes a wide overview of the most important topics, scientific fundamentals, and technical applications of metamaterials.Chapter coverage includes: the electrodynamics of left-handed media, synthesis of bulk metamaterials, synthesis of metamaterials in planar technology, microwave applications of metamaterial concepts, and advanced and related topics, including SRR- and CSRR-based admittance surfaces, magneto- and electro-inductive waves, and sub-diffraction imaging devices. A list of problems and references is included at the end of each chapter, and a bibliography offers a complete, up-to-daterepresentation of the current state of the art in metamaterials.Geared toward students and professionals alike, Metamaterials with Negative Parameters is an ideal textbook for postgraduate courses and also serves as a valuable introductory reference for scientists and RF/microwave engineers.

One must thus ensure that sampling produces the highest amount of information possible by carefully placing and weighting the limited set of samples. Furthermore, the integral evaluation should take into account not only the information brought by sampling but also possible information available prior to sampling, such as the integrand smoothness.

Rendering photorealistic images is a costly process which can take up to several days in the case of high quality images. In most cases, the task of sampling the incident radiance function to evaluate the illumination integral is responsible for an important share of the computation time. Therefore, to reach acceptable rendering times, the illumination integral must be evaluated using a limited set of samples. Such a restriction raises the question of how to obtain the most accurate approximation possible with such a limited set of samples. One must thus ensure that sampling produces the highest amount of information possible by carefully placing and weighting the limited set of samples. Furthermore, the integral evaluation should take into account not only the information brought by sampling but also possible information available prior to sampling, such as the integrand smoothness. This idea of sparse information and the need to fully exploit the little information available is present throughout this book. The presented methods correspond to the state-of-the-art solutions in computer graphics, and take into account information which had so far been underexploited (or even neglected) by the previous approaches. The intended audiences are Ph.D. students and researchers in the field of realistic image synthesis or global illumination algorithms, or any person with a solid background in graphics and numerical techniques.

Three construction workers. One buried secret. A system that was never meant to be found.When John, Richard, and Julio uncover a hidden box at a routine job site, they expect money, maybe something illegal—but manageable. What they find instead pulls them into something far more dangerous: a controlled network designed to monitor, manipulate, and eliminate anything that threatens its structure.At first, it feels like they're being watched. Then followed. Then… rewritten.As the system closes in, the lines between reality and control begin to blur. Richard disappears. Julio pays the price. And John is forced into a role he never chose—becoming the last variable in a system that doesn't tolerate deviation.But something goes wrong.

In a world where magic is no longer stable, power comes at a cost… and balance is everything.After surviving the chaos of the Vein of Hell and the rise of Lucifer's generals, the Zodiac heroes now face a far greater threat—something older than gods, deeper than magic itself.The First Magic is awakening.As the fabric of reality begins to collapse, the very powers that once made them strong now threaten to destroy everything. Stars fall, elements rebel, and the Constellation that once guided them begins to shatter.At the center of it all stands Kael—changed, evolving, and dangerously close to becoming something beyond human. Hunted by forces that seek to reclaim what he has become, he must decide whether to fight, surrender… or redefine what power truly means.

Power was never meant to be controlled.Only understood.After the chaos unleashed by Lucifer and the rise of forces beyond imagination, the Zodiac heroes find themselves facing a truth far more terrifying than any enemy—they are no longer fighting against destruction… but against the very nature of existence itself.Reality begins to fracture.Elements lose their balance.And something ancient—something whole—awakens.As the boundaries between light and darkness, creation and collapse begin to blur, alliances shift in unexpected ways. Even Lucifer is no longer just an enemy… but part of something far greater.Kael, Mira, and the others must confront a new kind of challenge—one where power alone is not enough. To survive, they must learn to guide, not dominate… to balance, not conquer.

Dans un monde où la nuit ne dort jamais, le pouvoir ne se conquiert pas… il se survit.Endovelico règne dans l'ombre, maître des ténèbres, porteur d'un pouvoir ancien qu'aucun être ne devrait posséder. Mais lorsque Aethel Veyne — une présence plus ancienne que le sang lui-même — revient pour réveiller ce qui sommeille en lui, tout bascule.Entre rêves brisés, manipulations mentales et guerres invisibles, Endovelico devra affronter bien plus qu'un ennemi : il devra affronter ce qu'il pourrait devenir.À ses côtés, Rafaela, seule capable de ramener l'homme derrière le roi.Et Luka, le loup marqué par une corruption qui cherche à le dévorer de l'intérieur.Mais certaines batailles ne se gagnent ni par la force… ni par le sang.Quand l'abîme vous regarde en retour,le véritable combat devient celui de votre propre âme.

The world didn't end.It evolved.After months of survival in the frozen north, Juliette and Gianluca Farioli find something they thought was gone forever:stability.A hidden community.Food. Shelter. Order.But peace comes with a price.Led by the enigmatic and unsettling Ricky, the so-called "e;Garden"e; offers protection from the infected… and from the chaos of the outside world.Tree-top sanctuaries.Underground bunkers.A system built to last.And at the center of it all—control.As Juliette carries a new life into a dying world, she becomes more than just a survivor.She becomes a symbol.A target.A future others want to shape.

In the depths of Blackridge Reserve, a legal hunting lodge hidden within an isolated forest, two friends arrive expecting a peaceful retreat. Vanessa, an English teacher seeking escape from routine, and Daniela, a disciplined military officer on vacation, are drawn into an environment that feels increasingly unsettling beneath its calm surface.When a hunting trip turns into a fatal accident, confusion quickly escalates into suspicion. Evidence does not match memory, and what should be a clear case begins to fracture under forensic scrutiny. As authorities close in, Vanessa finds herself accused of a crime she insists she did not commit, while Daniela's silence raises even deeper questions.Sheriff Tomson and Detective Cane are called to investigate, but the deeper they go, the more the forest itself seems to resist explanation. Hidden beneath Blackridge lies a forgotten military system—one designed to observe, manipulate, and predict human behavior within controlled terrain.

After meeting online, Daniel and Elena are drawn into an intense and immediate connection that feels destined, spiritual, and impossible to ignore. What begins as romance and curiosity quickly expands into something far more complex—an isolated courtyard community filled with hidden tensions, esoteric beliefs, and unspoken rules beneath its peaceful surface.When a sudden tragedy shatters the group, outside investigation begins to uncover deeper layers of manipulation, perception, and psychological influence. As Daniel becomes increasingly sensitive to patterns no one else seems to notice, reality itself begins to feel unstable.

The world is no longer collapsing.It is being erased.After a devastating ambush shatters the group, the J Family is torn apart—scattered across a world now ruled by fire, steel, and something far worse than the infected.As a new force rises from the ashes, the Magnus Company unleashes the Purification Protocol—a brutal campaign to eliminate all life touched by the infection. No survivors. No second chances.Juliette is forced north, alone, into a frozen wasteland where survival means more than just staying alive.Josh finds himself trapped inside the enemy's core, where the future of the infection is being rewritten—and where one decision could change everything.Julia begins to transform into something beyond human, forming a terrifying connection with the infected that could reshape the balance of power.

A man arrives in Seoul for an audition that should have been just another step in his career.But something about the room recognizes him in a way no script ever should.What begins as a simple casting process slowly unravels into something harder to define—an environment where roles feel pre-assigned, silence feels structured, and even absence seems to follow rules.As John moves deeper through the city and the strange production space known as Studio 3, he starts to lose the ability to separate what is happening to him from what is being observed about him. People from his past begin to reappear at the edges of this system, each one behaving as if they are part of something larger they cannot fully name.Renata, Andrea, Ricardo, Evelyn—each exists within a different layer of proximity to the same invisible structure. Some are inside it. Some are outside it. Some are no longer sure the difference matters.

The universe had rules.Not written.Not spoken.But absolute.Everything that exists—must belong.Everything that doesn't—is removed.For a time, that balance held.Worlds rose.Worlds fell.Civilizations burned across the stars.Hunters hunted.Devourers consumed.
