Asymptotic methods provide closed form expansions for diffracted fields and are also useful for eliciting physical interpretations of the various diffraction phenomena. One of the principle objectives of this text is to discuss the different asymptotic methods in a unified manner.
Numerically rigorous techniques for the computation of electromagnetic fields diffractred by an object become computationally intensive, if not impractical to handle, at high frequencies and one must resort to asymptotic methods to solve the scattering problem at short wavelengths. The asymptotic methods provide closed form expansions for the diffracted fields and are also useful for eliciting physical interpretations of the various diffraction phenomena. One of the principle objectives of this text is to discuss the different asymptotic methods in a unified manner. Although the book contains explicit formulas for computing the field diffracted by conducting or dielectric-coated objects, it also provides the mathematical foundations of the different methods and explains how they are interrelated.
