  • Multi-beam and multi-polarization electromagnetic wavefront shaping
    Patent number: 11575429
    Abstract: Methods and systems for shaping an electromagnetic wavefront are disclosed. A disclosed method includes tuning a tunable surface in an electromagnetic cavity and receiving the electromagnetic wavefront in the electromagnetic cavity. The electromagnetic wavefront includes a first wave defined by a first wavelength and a second wave defined by a second wavelength. The first wave and the second wave have a shared phase and a shared beam direction in the electromagnetic wavefront. The method further includes reflecting the electromagnetic wavefront within the cavity to repeatedly interact with the tunable surface, and transmitting, after reflecting the electromagnetic wavefront within the cavity, the electromagnetic wavefront from the electromagnetic cavity as a shaped electromagnetic wavefront. The first wave and the second wave have at least one of a difference in phase or a difference in beam direction in the shaped electromagnetic wavefront.

  • Antenna for transmitting and/or receiving an electromagnetic wave, and system comprising this antenna
    Patent number: 11329388
    Abstract: Antenna for transmitting and/or receiving an electromagnetic wave, including a radiating element, a tunable surface of variable impedance, and a controller connected to the tunable surface and which controls it based on a desired direction of the electromagnetic wave. The radiating element and the tunable surface are integrated inside a housing, the housing forming a cavity for the waves and including an opening for the electromagnetic wave to be transmitted to the outside.
