¡°This text is a cookbook for engineers who are attempting to implement FEM for the first time or in an area that may be unfamiliar. It is entirely applications oriented and strips away the laborious theory, making it easier to concentrate on quick and efficient usage.¡±

-- Microwave Journal, December 1998

¡°Those working in the area of microwave spectroscopy of dielectrics and microwave strip lines will find this a useful book for quickly characterizing electromagnetic waves.¡±

Now you can quickly and more easily work out challenging microwave engineering and high-frequency electromagnetic problems using the finite element method (FEM) with this practical book and software package. Using clear, concise text and dozens of real-world application examples, the book provides a detailed description of FEM implementation, while the software provides the code and tools needed to solve the three major types of EM problems: guided propagation, scattering, and radiation.

Valuable for practicing electrical engineers, R&D personnel new to FEM, and engineering students, the book provides a succinct overview of basic FEM concepts, outlines the capabilities and advantages of employing FEM methods, defines key finite elements, and describes various hybrid methods and absorbing boundary conditions. This unique book and software package enables you to:

Compute the dispersion diagram of arbitrarily shaped inhomogeneous isotropic lossless or lossy guiding structures

Analyze E- and H-plane waveguide discontinuities and devices

Understand the reflection from and transmission through simple 2-D inhomogeneous periodic structures, such as dichroics and photonic crystals

Analyze scattering from arbitrarily shaped inhomogeneous 2-D objects

Calculate the radiation diagram on principal planes of aperture antennas modeled as 2-D structures

Create geometric models using a fully functional 2-D mesh generator
Contents: Getting Started. Tools. Microwave Guiding Structures -- Characterization. Microwave Guiding Structures -- Discontinuities. Scattering and Antennas -- Hybrid Methods. Scattering and Antennas -- Absorbing Boundary Conditions. To Probe Further (a selected bibliography).

CD-ROM Included! Easy-to-use finite element software contains ready-made FORTRAN subroutines and source code that you can use immediately to solve a wide range of microwave and EM problems. The package is fully compatible with Internet freeware, so you can perform advanced engineering functions without having to purchase expensive pre- and post-processing tools.
