Abstract
A switch based on a phase change material including: a region in said phase change material that couples the first and second conductive electrodes of the switch; and a waveguide including a first end in line with a face of the region in said phase change material and a second end, opposed to the first end, designed to be illuminated by a laser source.
Claims10
A transmitarray cell or a reflectarray cell including a switch based on a phase change material comprising:
- a region in said phase change material that couples the first and second conductive electrodes of the switch;
- and
- a waveguide comprising a first end in line with a face of the region in said phase change material and a second end, opposed to the first end, designed to be illuminated by a laser source,
- wherein the waveguide further comprises, on the side of its second and first ends, input and output surfaces that respectively make it possible to receive and transmit a radiation in a direction orthogonal to the direction of propagation of the radiation through the waveguide;
- wherein the first and second conductive electrodes are parts of an antenna element of a cell of a transmitarray or of a reflectarray.
