Abstract
PATCH is a frequency domain electromagnetic scattering code based on a method-of-moments solution to the Electric Field Integral Equation (EFIE). The numerical methods are based on an earlier version of the code. The present code has the following capabilities: computation of scattering from multiple bodies, treatment of multiple intersecting surfaces, use of symmetry planes to reduce the number of unknowns, treatment of surfaces with lumped and distributed impedance loads, and the capability for plane wave or voltage source excitation. A primitive mesh generator has been included to ease the problem of input data generation. The outputs of the code are the currents on the body, radiated fields, far fields, radar cross section, and Thevenin equivalent circuits. Furthermore, thin wires attached to conducting surfaces may be modeled by use of an equivalent thin strip.
