Characterization of Quasi-Optical Filters with Picosecond Transient Radiation

The broad-band microwave transmission properties of quasi-optical components are characterized with optoelectronically generated, picosesond transient radiation. The polarization sensitivity of a lithographically fabricated wire grating, from 15–140 GHz, is presented. The complex transmission functions of two different uniform arrays of cross dipoles are measured and compared with theoretical predictions. © 1992 IEEE
