Paper Abstract

This paper presents a proposal for a quasi-optical design for a terahertz band multi-channel front-end that has the potential application in China's future 5m terahertz telescope in Dome A, Antarctica. The front-end provides quasioptical beam coupling between the Cassegrain antenna system and the heterodyne receiver arrays operating in two bands simultaneously. Numerical verification of the design was performed using the Gaussian optics and parallelized physical optics algorithms.
