Infinite-Space Dyadic Green Functions in Electromagnetism 1st Edition

In any linear system the input and the output are connected by means of a linear operator. When the input can be notionally represented by a function that is null valued everywhere except at a specific location in spacetime, the corresponding output is an entity called the Green function in field theories. Dyadic Green functions are commonplace in electromagnetics, because both the input and the output are vector functions of space and time. Numerous research papers have been written on dyadic Green functions when both the input and the output are time harmonic and a linear homogeneous medium occupies all space. This book provides a self-contained survey of the state-of-the-art knowledge of infinite-space dyadic Green functions.
