Description

Analytical Modeling in Applied Electromagnets encompasses the most complete treatment on the subject published to date, focusing on the nature of models in radio engineering. This leading-edge resource brings you detailed coverage of the latest topics, including metamaterials, photonic bandgaps and artificial impedance surfaces, and applies these concepts to a wide range of applications. The book provides you with working examples that are mainly directed to antenna applications, but the modeling methods and results can be used for other practical devices as well.You get an in-depth discussion of the basic building blocks of every radio system. The analysis includes classical and well-studied topics such as highly conducting surfaces and layers of various materials, as well as the more novel or alternative structures being applied today. Packed with over 750 equations, this authoritative reference is ideal for both practicing electrical engineers and serious graduate students in related courses.
