The Fascinating World of Advanced Electromagnetics And Scattering Theory

Electromagnetics is an intriguing field, encompassing the study of electromagnetic radiation and its interactions with matter. Within this broad field, one area of utmost importance is Advanced Electromagnetics and Scattering Theory, which explores the behavior of electromagnetic waves when encountering various objects or materials.

What is Electromagnetic Scattering?

Electromagnetic scattering refers to the phenomenon where incident electromagnetic waves encounter an object and interact with it, resulting in a change in the wave's direction, intensity, and polarization. This interaction can occur with objects of various shapes, sizes, and compositions. Scattering theory helps us understand and predict the behavior of these waves when interacting with such objects.

Applications of Advanced Electromagnetics and Scattering Theory

This book present the lecture notes used in two courses that the late Professor Kasra Barkeshli had offered at Sharif University of Technology, namely, Advanced Electromagnetics and Scattering Theory. The prerequisite for the sequence is vector calculus and electromagnetic fields and waves. Some familiarity with Green's functions and integral equations is desirable but not necessary.

The book provides a brief but concise to classical topics in the field. It is divided into three parts including annexes. Part I covers principle of electromagnetic theory. The discussion starts with a review of the Maxwell's equations in differential and integral forms and basic boundary conditions. The solution of inhomogeneous wave equation and various field representations including Lorentz's potential functions and the Green's function method are discussed next. The solution of Helmholtz equation and wave harmonics follow. Next, the book presents plane wave propagation in dielectric and lossy media and various wave velocities. This part concludes with a general discussion of planar and circular waveguides.
Part II presents basic concepts of electromagnetic scattering theory. After a brief discussion of radar equation and scattering cross section, the author reviews the canonical problems in scattering. These include the cylinder, the wedge and the sphere. The edge condition for the electromagnetic fields in the vicinity of geometric discontinuities are discussed. The author also presents the low frequency Rayleigh and Born approximations. The integral equation method for the formulation of scattering problems is presented next, followed by an to scattering from periodic structures.
Part III is devoted to numerical methods. It begins with finite-difference methods to solve elliptic equations, and introduces the finite-difference time-domain method for the solution of hyperbolic and parabolic equations. Next, the part turns to the method of moments for the solution of integral equations. This part ends with a short to the finite-element method.
