STUDY AND INVESTIGATION OF MILLIMETER AND SUB MILLIMETER WAVE RECEIVER TECHNIQUES
Abstract
The development of video detection techniques which are usable in the millimeter and submillimeter wave range of the spectrum. A pyroelectric detector which uses tri-glycine sulfate as the detecting material has been developed and tested in microwave systems at wavelengths of 8.15 mm, 4.10 mm, and 2.14 mm. The minimum detectable power with the present configuration is 8 micro watts at the nger wavelengths and between 20 and 200 microwatts at 2.14 mm. A similar de tector using barium titanate as the detecting material did not prove to be as sensitive as the tri-glycine sulfate unit. An analysis for the metal reflecting beam wave guide has been developed. It is found that the reflectors should be sections of oblate spheroids. An experimental wall current detector for use with the beam wave guide has been built. Initial tests were encouraging.
