High Frequency Electromagnetic Propagation/Scattering Codes

Abstract

Whenever band-limited signals are measured or generated, different distributions of a fixed number of receivers and transducers lead to very different resolutions. A closely related set of issues is encountered in the numerical solution of scattering problems: given a scatterer, one would like to find nodes on its surface leading to most efficient discretizations. In this project, we have constructed numerical algorithms for the determination of such discretizations in one, two, and three dimensions, and used the obtained results for the design of optimal phased antenna arrays. The work will be reported in four papers; copies of two of these papers are attached, and two are in preparation. Also, a preliminary patent application has been submitted.
