This book provides a brief overview of the popular Finite Element
Method (FEM) and its hybrid versions for electromagnetics with
applications to radar scattering, antennas and arrays, guided
structures, microwave components, frequency selective surfaces,
periodic media, and RF materials characterizations and related
topics. It starts by presenting concepts based on Hilbert and
Sobolev spaces as well as Curl and Divergence spaces for generating
matrices, useful in all engineering simulation methods. It then
proceeds to present applications of the finite element and finite
element-boundary integral methods for scattering and radiation.
Applications to periodic media, metamaterials and bandgap
structures are also included. The hybrid volume integral equation
method for high contrast dielectrics and is presented for the first
time. Another unique feature of the book is the inclusion of design
optimization techniques and their integration within commercial
numerical analysis packages for shape and material design. To aid
the reader with the method's utility, an entire chapter is devoted
to two-dimensional problems. The book can be considered as an
update on the latest developments since the publication of our
earlier book (Finite Element Method for Electromagnetics, IEEE
Press, 1998). The latter is certainly complementary companion to
this one.
This text/reference is a detailed look at the development and use
of integral equation methods for electromagnetic analysis,
specifically for antennas and radar scattering. Developers and
practitioners will appreciate the broad-based approach to
understanding and utilizing integral equation methods and the
unique coverage of historical developments that led to the current
state-of-the-art. In contrast to existing books, "Integral Equation
Methods for Electromagnetics" lays the groundwork in the initial
chapters so students and basic users can solve simple problems and
work their way up to the most advanced and current solutions. This
is the first book to discuss the solution of two-dimensional
integral equations in many forms of their application and utility.
As 2D problems are simpler to discuss, the student and basic reader
can gain the necessary expertise before diving into 3D
applications. This is also the first basic text to cover fast
integral methods for metallic, impedance, and material geometries.
It will provide the student or advanced reader with a fairly
complete and up-to-date coverage of integral methods for composite
scatterers.
