Abstract

The invention discloses a terahertz dynamic phase modulator based on waveguide insertion microstructures, which comprises a rectangular waveguide directional coupler and an even number of insertion microstructures with identical structures, and is characterized in that the rectangular waveguide directional coupler has four ports including an input port, an output port, a first reflection port and a second reflection port, the even number of insertion microstructures are inserted into the rectangular waveguide and located at the first reflection port and the second reflection port respectively, and each insertion microstructure comprises a substrate, and an insertion metal structure, a metal strip structure, a gallium arsenide variable capacitance diode, a grounding metal structure and a feed metal structure which are arranged on the substrate. According to the invention, continuous and dynamic terahertz phase regulation and control can be provided, and low insertion loss can be maintained at the same time.

Description

technical field [0001] The invention relates to a dynamic phase modulation device used in the terahertz band, in particular to a terahertz dynamic phase modulator based on a waveguide insertion microstructure, belonging to the technical field of electromagnetic functional devices. Background technique [0002] Terahertz waves are electromagnetic waves with a frequency range of 0.1THz to 10THz. The frequency of terahertz waves is above millimeter waves and below infrared. The latter two have been developed relatively maturely, while the former is still at the forefront of research. . It plays a role in promoting the development of disciplines such as physics, chemistry, astronomy, informatics and life sciences, and has shown outstanding performance in the fields of high-speed communication, high-precision imaging, biological detection technology, outer space space technology, radar technology, and high-tech anti-terrorism. It has a huge potential utilization value and is a t...
