This work presents a comprehensive description of the basic principles and practical application of the conjugate gradient method in combination with fast Fourier transform (CG-FFT). It provides extensive fundamental analyses of basic spectral methods and conjugate gradient methods. The presentation details the relationship between applied electromagnetics and linear system theory for the analysis of radiation and scattering from: two-dimensional and three-dimensional bodies with arbitrary geometry and material composition; plane, multilayer or volumetric periodic structures; and metallic pateches defined over body of revolution (BOR) surfaces. This work is augmented with 860 equations, 185 figures and 250 references.
