Mikhail Sergeev - Böcker

The book introduces the basic foundations of high mathematics and vector algebra. Then, it explains the basic aspects of classical electrodynamics and electromagnetism. Based on such knowledge readers investigate various radio propagation problems related to guiding structures connecting electronic devices with antenna terminals placed at the different radar systems. It explains the role of antennas in process of transmission of radio signals between the terminals. Finally, it shows the relation between the main operational charactistics of each kind of radar and the corresponding knowledge obtained from the previous chapters.

A GUIDE TO THE FUNDAMENTAL THEORY AND PRACTICE OF OPTICAL COMMUNICATIONFiber Optic and Atmospheric Optical Communication offers a much needed guide to characterizing and overcoming the drawbacks associated with optical communication links that suffer from various types of fading when optical signals with information traverse these wireless (atmospheric) or wired (fiber optic) channels.The authors—noted experts on the topic—present material that aids in predicting the capacity, data rate, spectral efficiency, and bit-error-rate associated with a channel that experiences fading. They review modulation techniques and methods of coding and decoding that are useful when implementing communications systems. The book also discusses how to model the channels, including treating distortion due to the various fading phenomena. Light waves and their similarity to radio waves are explored, and the way light propagates through the atmosphere, through materials, and through the boundary between two materials is explained. This important book: Characterizes principal optical sources and detectors, including descriptions of their advantages and disadvantages, to show how to design systems from start to finishProvides a new method of predicting and dealing with the dispersive properties of fiber optic cables and other optical guiding structures in order to increase data stream capacityHighlights effects of material and multimode (multi-ray) dispersion during propagation of optical signals with data through fiber optic channelsPresents modulation techniques and methods of coding and decoding that are useful when implementing communications systems Written for professionals dealing with optical and electro-optical communications, Fiber Optic and Atmospheric Optical Communication explores the theory and practice of optical communication both when the optical signal is propagating through the atmosphere and when it is propagating through an optical fiber.

In Theory of Religious Cycles: Tradition, Modernity and the Bahá’í Faith Mikhail Sergeev offers a new interpretation of the Soviet period of Russian history as a phase within the religious evolution of humankind by developing a theory of religious cycles, which he applies to modernity and to all the major world faiths of Judaism, Buddhism, Christianity, and Islam.Sergeev argues that in the course of its evolution religion passes through six common phases—formative, orthodox, classical, reformist, critical, and post-critical. Modernity, which was started by the European Enlightenment, represents the critical phase of Christianity, a systemic crisis that could be overcome with the appearance of new religious movements such as the Bahá’í Faith, which offers a spiritual extension of the modern worldview.
