ABSTRACT
In this chapter we use the method of moments to analyze radiation and scattering by three-dimensional surfaces of arbitrary shape. Problems of this kind appear in many areas of practical interest such as electromagnetic interference (EMI), electronic packaging, radar cross section, and antenna design. This area has received significant attention in the literature in the last thirty years, and many different methods of treating three-dimensional surfaces have been considered. Until recently, most threedimensional problems were limited to a relatively small electrical size, given the limitations of commonly available computers and system memory. Solving larger problems typically required access to supercomputer-class equipment, which was not readily available to most people. With the advances in processing speed, memory and operating systems in the last 10 years, larger problems can now be solved on modest desktop computers. This has opened up areas of study that were not attempted or even considered before. The development of the fast multipole method has further increased the tractability of the larger problems, and we discuss its application to MOM problems in detail in Chapter 8.
