Modern Electromagnetic Scattering Theory with Applications

This self-contained book gives fundamental knowledge about scattering and diffraction of electromagnetic waves and fills the gap between general electromagnetic theory courses and collections of engineering formulas. The book is a tutorial for advanced students learning the mathematics and physics of electromagnetic scattering and curious to know how engineering concepts and techniques relate to the foundations of electromagnetics

Modern Electromagnetic Scattering Theory with Applications

List of Abbreviations

Vectors are denoted by bold letters ( a ). The scalar product of two vectors is denoted by dot ( a · b ), and the vector product is denoted by cross ( a × b ). Unit vectors are denoted as , , etc. The double bar over a character denotes a 2 by 2 matrix or a second-order tensor (). Transposition of a vector or a matrix is denoted by the superscript T, e.g. . Time-harmonic dependence is in the form exp ( j t ).

Values related to incident wave are denoted using index "inc" and those related to scattered waves are marked by index "sc".

Asymptotic behaviour at large values of arguments ( p real valued):

o ( kp ) means that lim k o ( kp ) k - p = 0;

O ( kp ) means that there exists a finite constant C such that lim k O ( kp ) k - p C .

X (dB) is equal to 20 log 10 X if X is amplitude-related and to 10 log 10 X if X is power-related.
