  • Patent number: 12113259
    Abstract: Low-loss terahertz switches with nanometer resolution positioning and feedback are disclosed. In one embodiment, the switch uses a U-bend waveguide surrounded by an electromagnetic band gap and is implemented in a fully metal-machined fashion in combination with a piezo-electric motor and an optical linear encoder. In another embodiment, the switch comprises a MEMS device.
    Type: Grant

  • Publication number: 20220267140
    Abstract: A phased array system comprising an array of antennas outputting or receiving electromagnetic radiation to or from a steerable direction, wherein the electromagnetic radiation is at submillimeter wavelengths. The system further comprises a plurality of waveguides outputting or receiving the signals to or from the antennas, each of the waveguides with individual phase tuning. The waveguides are configured and dimensioned to guide an electromagnetic wave comprising the signals having a frequency in a range of 100 gigahertz (GHz) to 1000 terahertz (THz). The system further comprises means for phase shifting the signal by means of shifting or varying one or more phases of the signals relative to one another so as to vary, steer, or scan a direction of the electromagnetic radiation.
