A Quasi-optical resonator with new coupling method and
parasitic-mode-suppressing in 110 ~ 170GHz
Abstract
In this paper, a quasi-optical resonator with new coupling method and
parasitic-mode-suppressing in 110~170GHz is proposed.
The coupling of THz quasi-optical resonator in this paper is realized by
PCB substrate processing and pressurized flange. At the same time, the
parasitic mode is effectively suppressed by slitting the plane mirror to
reduce the influence on the main mode during the test. And fused quartz
sample was tested to verify the feasibility of the system for complex
dielectric testing of materials in 110~170GHz.
