Abstract
We consider a volume V bounded by a perfectly conducting surface S, as depicted in Fig. 9.1. Prescribed sources J excite the electromagnetic field (E, H) inside the volume V, which is usually referred to as an electromagnetic cavity. The field in the cavity is the solution of Eqs. (4.45) with boundary condition \(\hat{\textbf{n}}\times \textbf{E} = 0\) over the surface S. The sources radiate inside the cavity, and the cavity field can be modeled as a superposition of the direct field and the multiply diffracted field due to the cavity wall. For this reason the problem can be addressed as interior scattering.
