Electromagnetic Fields In Cavities

A thorough and rigorous analysis of electromagnetic fields in cavities This book offers a comprehensive analysis of electromagnetic fields in cavities of general shapes and properties. Part One covers classical deterministic methods to conclude resonant frequencies, modal fields, and cavity losses; quality factor; mode bandwidth; and the excitation of cavity fields from arbitrary current distributions for metal-wall cavities of simple shape. Part Two covers modern statistical methods to analyze electrically large cavities of complex shapes and properties. Electromagnetic Fields in Cavities combines rigorous solutions to Maxwell's equations with conservation of energy to solve for the statistics of many quantities of interest: penetration into cavities (and shielding effectiveness), field strengths far from and close to cavity walls, and power received by antennas within cavities. It includes all modes and shows you how to utilize fairly simple statistical formulae to apply to your particular problem, whether it's interference calculations, electromagnetic compatibility testing in reverberation chambers, measurement of shielding materials using multiple cavities, or efficiency of test antennas. Electromagnetic Fields in Cavities is a valuable resource for researchers, engineers, professors, and graduate students in electrical engineering.

Professor Jean Van Bladel, an eminent researcher and educator in fundamental electromagnetic theory and its application in electrical engineering, has updated and expanded his definitive text and reference on electromagnetic fields to twice its original content. This new edition incorporates the latest methods, theory, formulations, and applications that relate to today's technologies. With an emphasis on basic principles and a focus on electromagnetic formulation and analysis, Electromagnetic Fields, Second Edition includes detailed discussions of electrostatic fields, potential theory, propagation in waveguides and unbounded space, scattering by obstacles, penetration through apertures, and field behavior at high and low frequencies.

Only 30% Of This Book Deals With Theory, The Rest Of It Is Application Of This Theory To Various Situations Of Different Levels Of Complexity. In Each Case The Reason For The Choice Of The Method Is Explained, And Various Doubts Which Assail The Minds Of Most Students Have Been Tackled. The Solved Examples In The Book Do Not Deal With Mere Substitution Of Numerical Values Of Formulae. They Are Aimed At Establishing A Strong Foundation Of Knowledge.All The Required Mathematics Has Been Explained In The First Chapter To Avoid The Need To Refer Frequently To Other Books In Mathematics. At The End Of Each Chapter A Summary Of The Achievements Is Given Along With Comments On The Nature Of Difficulties Encountered, And The Reader Is Thereafter Prepared For The Objectives To Be Attained In The Following Chapter. The Emphasis Throughout The Book Is On A Physical Understanding Of Fields And Waves And Their Characteristics, Rather Than Getting Lost In A Maze Of Mathematical Manipulations.This Is An Introductory Textbook Intended To Give The Reader A Solid Grounding In The Subject And To Prepare Him To Deal With More Advanced Texts. The Material Has Been Tested In One-Semester Courses Given By The Author In Various Colleges In Pune.
