Abstract

The invention discloses a terahertz MEMS reconfigurable power divider and a realization method thereof. In the present invention, the first and second rectangular waveguides are arranged at the upper end of the first coupling waveguide, the third and fourth rectangular waveguides are arranged at the lower end of the second coupling waveguide, and the first and second waveguides are connected through the first and second cascaded waveguides. The coupling waveguide constitutes a terahertz waveguide power divider, and MEMS angle actuators are embedded in the first and second coupling waveguides, and the rotation angle of the metal surface is controlled by applying a bias voltage to the bimorph cantilever beam array of the MEMS angle actuator; Set the voltage to adjust the angle of the MEMS angle actuator to realize the continuous adjustment of the output power ratio of the terahertz waveguide power splitter. At the same time, there are terahertz equal power splitters, terahertz 10dB couplers and terahertz The function of the switch; it has the advantages of power adjustment and function multiplexing, and can be applied to the gain adjustment, beam scanning and shaping of the terahertz array antenna.

Description

technical field [0001] The invention relates to terahertz technology, in particular to a terahertz MEMS reconfigurable power divider and a realization method thereof. Background technique [0002] Terahertz (THz) waves generally refer to electromagnetic waves with frequencies in the range of 0.1 to 10 THz (wavelength of 3000 to 30 μm), which overlap with millimeter waves in the long waveband and infrared light in the short waveband. The theoretical transition zone is also the transition zone from electronics to photonics. With the characteristics of wide frequency band, strong penetration, short wavelength and low energy, it can realize hundreds of times of data capacity and communication rate of 5G, and realize anti-stealth high-resolution radar, high-precision positioning imaging, non-destructive testing and other functions. Terahertz technology has great scientific value and broad application prospects in object imaging, environmental monitoring, radio astronomy, broadba...
