US Patent Issued to California Institute of Technology on June 3 for "Broadband polarization splitting based on volumetric meta-optics" (California Inventors)

ALEXANDRIA, Va., June 4 -- United States Patent no. 12,320,988, issued on June 3, was assigned to California Institute of Technology (Pasadena, Calif.).

"Broadband polarization splitting based on volumetric meta-optics" was invented by Gregory Roberts (Pasadena, Calif.) and Andrei Faraon (Pasadena, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods and devices to split electromagnetic waves across broad bandwidths in correspondence with predefined polarization state vectors are disclosed. The described methods can be used cameras or image sensors measuring directly the polarization states of an incident electromagnetic waves. The devices include three-dimensional (3D) scattering structures made of...
