Abstract
Arbitrary incident fields can be expressed rigorously in terms of Gaussian elements distributed self-consistently over a discrete lattice in a (configuration)-(spatial wavenumber) phase space. The authors note the results of calculations performed to evaluate the field transmitted from a cosine and sine (nulling) one-dimensional aperture through a cylindrical radome. The Gaussian basis elements used were wide and narrow, tilted and nontilted, with various aperture locations. It was found that summing over the important elements in the phase-space lattice produces the same results in all narrow beam cases. Illustrative results obtained with narrow beams are shown and they confirm the utility of the tracking scheme.Keywords
