Abstract

The invention provides a terahertz quasi-optical frequency multiplier, comprising a first blocking capacitor, a filter, a frequency multiplying antenna and a quasi-optical device, wherein the frequency multiplying antenna comprises an antenna and a nonlinear device, an input signal passes through the first blocking capacitor and the filter and then is loaded on the frequency multiplying antenna, and each harmonic component of the input signal is restrained by the filter after the input signal passes through the filter; the nonlinear device of the frequency multiplying antenna generates harmonic components to the input signal loaded on the frequency multiplying antenna; the antenna of the frequency multiplying antenna radiates required output signals; and the output signals are endowed with better directivity by virtue of the quasi-optical device. The terahertz quasi-optical frequency multiplier is small in size and light in weight, can easily implement space power synthesis and can serve as an efficient odd frequency multiplier.

Description

technical field [0001] The invention relates to the technical field of terahertz wave sources, in particular to a terahertz quasi-optical frequency doubler. Background technique [0002] Terahertz is the last segment of the electromagnetic spectrum to be exploited. The unique properties of terahertz radiation make terahertz imaging technology one of the research hotspots today. The terahertz source has always been one of the key components of the terahertz system. Terahertz signals can be generated by vacuum electronic devices, or local oscillator signals can be generated by combining low-frequency sources with frequency doublers. It is a relatively common way to generate a terahertz signal with a low-frequency source combined with a multiplied frequency. Compared with vacuum electronic device sources, this method has the advantages of small size and light weight; at the same time, phase locking and modulation of terahertz signals can be realized through phase locking and...
