1. A method for wireless communications, comprising:
determining, based on an operating frequency, a beamformer to apply to groups of two or more of elements of a reconfigurable intelligent surface (RIS); and
applying the beamformer to the groups of elements of the RIS to facilitate communications at the operating frequency by re-radiating radio signals via the elements of the RIS,
wherein at least one of the groups of elements of the RIS has a total area A′ inversely proportional to the operation frequency squared.
