Design, Modeling, and Fabrication of a Quasi-Optical Power Combiner Based on the Talbot Effect
Abstract
This document is a final technical report describing the work completed under the Short-Term Research Initiative (STIR) contract (DAAG55-98-1-0440) awarded to Texas Christian University (TCU) by the U.S. Army Research Office on 20 July 1998. The work was carried out in collaboration with Professor Michael Steer's research group at the North Carolina State University (NCSU). The objective of this effort was to investigate the feasibility of quasi-optical power combiners based on the Talbot effect. At TCU, planar waveguide structures were designed in the X-band (8-12.4 GHz). Waveguide structures were constructed in Rexolite 1422 and characterized at NCSU. Although the optimum designs were not fabricated due to waveguide material limitations, the electromagnetic field data indicated the structure and high degree of symmetry associated with multimode interference phenomena. This favorable result is key to the demonstration of a quasi-optical power combiner based on the Talbot effect.
