Quasioptical sectional waveguide transition of submillimeter waveband

Abstract

In this paper, the results of investigation of sectional waveguide transition (SWT) are presented. The transition is intended for mating of quasioptical track with wideband optical-acoustic receiver (OAR). The track is realized on the base of "hollow dielectric waveguide" transmission line. SWT ensures transmission of electromagnetic energy from HDW to OAR in a broad band of frequencies (600-900 GHz) with relatively low losses at essential (up to 23%) reduction of transition length, as compared with appropriate linear transition. Thus manufacturability and low cost are kept.
