The subject of computation in electricity and magnetism has so advanced in the past 40 years, since the advent of digital computers and thanks to the development of numerical methods, that today it urges and deserves adequate collocation also in curricula for electrical engineering.

The aim is that of writing a textbook containing the necessary background, i.e. laws explaining electromagnetic phenomena, mathematical operators and equations as well as methods for electromagnetic ?eld calculation. The latter include both analytical and numericalmethods applied to the analysis as well as to the synthesis of electromagnetic devices.

The key theme of this book is an exploration of how recent advances across three related scientific fields are intertwined - the developments in metamaterials, the automated optimal design of innovative electronic, electromagnetic and mechatronic devices, and 3D printing.Developments in the field of automated optimal design have enabled the design of innovative electronic, electromagnetic and mechatronic devices, but there is a risk that design uncertainties and fabrication tolerances dictated by conventional manufacturing techniques will limit the practical synthesis and industrial realisation of these novel designs. The solution might be found in new manufacturing possibilities offered by 3D printing technologies and techniques for the fabrication of conductive layers in low and high frequency applications.The book approaches the topic from several perspectives, including the design of 3D fields, advances in shape synthesis, the role of additive manufacturing in synthesising metamaterials and manipulating ferromagnetic materials, and the steps from numerical models to printed mechatronic devices. A final chapter discusses design challenges and opportunities in industrial settings.Led by two expert editors, with contributions from authors with a range of backgrounds across academia and industrial research, this book provides key information for researchers, advanced students and industry professionals in advanced manufacturing, mechatronics, and electrical and electronic engineering.

This book highlights numerical models as powerful tools for the optimal design of Micro-Electro-Mechanical Systems (MEMS). Most MEMS experts have a background in electronics, where circuit models or behavioral models (i.e. lumped-parameter models) of devices are preferred to field models. This is certainly convenient in terms of preliminary design, e.g. in the prototyping stage. However, design optimization should also take into account fine-sizing effects on device behavior and therefore be based on distributed-parameter models, such as finite-element models. The book shows how the combination of automated optimal design and field-based models can produce powerful design toolboxes for MEMS. It especially focuses on illustrating theoretical concepts with practical examples, fostering comprehension through a problem-solving approach. By comparing the results obtained using different methods, readers will learn to identify their respective strengths and weaknesses. In addition, special emphasis is given to evolutionary computing and nature-inspired optimization strategies, the effectiveness of which has already been amply demonstrated. Given its scope, the book provides PhD students, researchers and professionals in the area of computer-aided analysis with a comprehensive, yet concise and practice-oriented guide to MEMS design and optimization. To benefit most from the book, readers should have a basic grasp of electromagnetism, vector analysis and numerical methods.

Multiobjective Shape Design in Electricity and Magnetism is entirely focused on electric and magnetic field synthesis, with special emphasis on the optimal shape design of devices when conflicting objectives are to be fulfilled.
