Abstract

The invention discloses a terahertz waveguide polarization attenuating device, comprising a housing, an electromagnetic wave transceiving unit arranged in the housing, a first off-axis paraboloid mirror, a second off-axis paraboloid mirror, a polarization grid, a turntable and a microwave absorbing assembly. The device has the advantages of wide working band range, large attenuation dynamic range,high attenuation precision and large bearing power, and each module of the device can be conveniently disassembled. In the case of large frequency range span, the module can be simply replaced to form the attenuation device in the required frequency band.

Description

technical field [0001] The present invention relates to polarization attenuators. More specifically, it relates to a terahertz waveguide polarization attenuation device. Background technique [0002] The waveguide attenuator is a commonly used microwave passive device, which is mainly used to adjust the signal power. It is widely used in the fields of measurement calibration, test research and development in the laboratory. The traditional rotary polarization attenuator is composed of a square-circle transition waveguide at both ends and a circular waveguide section in the middle. In the square-circle transition waveguide at both ends, there is an absorbing plate parallel to the wide wall of the waveguide, while the absorbing plate in the circular waveguide can be Rotate around the vertical axis. The attenuation is controlled by rotating the angle between the absorber in the circular waveguide and the horizontal plane. With the increase of application frequency, especiall...
