Title:
DEVICES AND METHODS FOR CONTROLLABLY REFLECTING ELECTROMAGNETIC WAVES
Document Type and Number:
WIPO Patent Application WO/2024/045150
Kind Code:
A1
Abstract:
A device (10) for controllably reflecting electromagnetic (EM) waves is provided. The device (10) includes a metasurface (30) having an array of electromagnetic unit cells (32). The device (10) further includes a controller (20) for controlling, based on an angle of incidence of the EM waves relative to the metasurface (30) and based on a desired anomalous angle of reflection of the EM waves relative to the metasurface (30), a reflection phase of each unit cell (32) of a supercell (34) of the metasurface (30) to control an angle of reflection of the EM waves relative to the metasurface (30) to be the desired anomalous angle of reflection. The supercell (34) consists of one or more of the unit cells (32), and a size (D) of the supercell (34) in a direction of a plane of propagation of the EM waves is at least 2λ, wherein λ is a wavelength of the EM waves.
