Variable reflect array, and method for designing variable reflector array

A method for designing a variable reflect array wherein

• the reflect array comprises;
• a substrate unit having a supercell side;
• and
• a plurality of supercells disposed on the supercell side of the substrate unit with an interval between adjacent supercells of the plurality of supercells, each of the plurality of supercells having an incidence angle and a reflection angle with respect to electromagnetic waves of a predetermined wavelength,
• wherein each of the plurality of supercells includes a dielectric substrate and a plurality of unit cells disposed on a surface of the dielectric substrate, and,
• the plurality of unit cells comprise an antenna,
• the method for designing a variable reflect array comprises:
• a step of designing the plurality of supercells comprising the plurality of unit cells, and,
• a step of changing one of the incidence angle and the reflection angle while keeping the other of the incidence angle and the reflection angle, by changing the interval between the plurality of supercells, being configured to be executed after the step of designing the supercells.
