Abstract

The invention discloses a terahertz waveguide filter based on a dual-mode resonant cavity and a design method thereof, belonging to the technical field of terahertz solid-state circuits. The filter includes an input waveguide, a first diaphragm, a first resonant cavity, a second diaphragm, a second resonant cavity, a third diaphragm, and an output waveguide arranged in sequence; The relative position of the adjacent diaphragms introduces an independently controllable transmission zero point in the upper stopband or lower stopband of the filter, which greatly improves the square coefficient of the filter and has excellent filtering performance; and the filter has a small The width-to-depth ratio and the overall structure are symmetrical about the E plane, which can effectively reduce the processing difficulty and improve the device yield, which is very suitable for high-precision and low-cost CNC milling technology; at the same time, the filter design method provided by the present invention can realize the filter design method. rapid design of the device.

Description

technical field [0001] The invention belongs to the technical field of terahertz solid-state circuits, and relates to a terahertz waveguide filter based on a dual-mode resonant cavity and a design method thereof. Background technique [0002] Terahertz waves refer to electromagnetic waves in the frequency range of 0.1 THz-10 THz. Terahertz waves are adjacent to millimeter waves in the long wavelength band, and intersect with infrared rays in the short wavelength band, which is at the intersection of macro-electronics and micro-photonics. Nowadays, because of its unique advantages in many application fields such as object imaging, communication, astronomical observation, and food detection, a scientific research upsurge of terahertz wave research has been formed. [0003] Terahertz waves have many characteristics that microwave millimeter waves and visible light do not have, which have attracted extensive attention of many researchers. The unique properties of terahertz wav...
