Nonuniform bandlimited basis functions in the analysis of axisymmetric reflector antennas

Abstract

The use of bandlimited sampling-like basis functions on different kinds of nonuniform grids is investigated in conjunction with Method of Moments integral equation solution to the problem of scattering from axially symmetric reflectors. Particular attention is given to the description of currents near the edge of reflector surface. Supporting numerical examples are provided using classical reflector.
