This practical, new book provides a wide choice of analytical solutions to problems faced by antenna design engineers and researchers working in electromagnetic modeling. Based on leading-edge method-of-moments procedures, the book presents new theories and techniques that help professionals optimize performance in numerical analysis of composite metallic and dielectric structures in the complex frequency domain. For the first time, comparisons and new combinations of techniques bring the elements of flexibility, ease of implementation, accuracy, and efficiency into clear focus for all practitioners. A wide range of examples are given - from simple to complex - including scatterers, antennas and microwave circuits. Intricate models include TV UHF pannels, horn, parabolic, microstrip patch antennas, and many others.
