A recently developed compression and sparse solution strategy for electromagnetic problems is applied to integral-equation formulations of scattering from perfectly conducting targets in three dimensions. It is shown that the resulting representations of both the impedance matrix and its inverse are

β¦ Synopsis
The radiation field patterns of rectangular waveguides and horns of finite dimensions are obtained numerically. The electric field integral equation is formulated to relate their radiation patterns to the surface current distribution. These currents are determined numerically by reducing the integral equation to a matrix equation, using the moment method. The computed currents are then used to calculate the radiation patterns and cross-polar fields of the finite waveguides and horns. The method is numerically efficient and can be applied to the computation and optimization of the antenna feed configurations.

This paper gives a brief account of the formulation of the Helmholtz integral equation specialized to the case of an axisymmetric body in free space. In this case the surface integral of the Helmholtz integral equation may be reduced to a combination of a line integral and an integral over the angle
The formulation of acoustic radiation from multiple vibrating bodies of arbitrary shape by the Helmholtz integral equation is presented. A computer code was developed to calculate the sound pressure field around an arbitrary number of three-dimensional vibrating bodies of arbitrary shape. The near f
