A Simple Model for Radiation and Scattering from Wires and Surfaces

Abstract

A new method for evaluating the free space im­ pedance functions which appear in the method of mements for linear and aperture antennas is described. The results are simple expressions in closed form suitable for machine computation. The impedance functions were evaluated using two computer programs. The calculated results are in good agreement with existing data. Computation time is short and the results are accurate.
