Publication number: 20190113775Abstract: Complex wavefront engineering is realized through a random metasurface phase mask backed by a phase-only spatial light modulator. The metasurface consists of an array of subwavelength nanoscatterers which give the metasurface a pre-arranged disorder. Since the transmission matrix of the disordered metasurface is known, there is no need for extensive characterization measurements which are instead required in standard disordered optical devices.Type: ApplicationFiled: April 19, 2018Publication date: April 18, 2019Inventors: Mooseok JANG, Yu HORIE, Atsushi SHIBUKAWA, Andrei FARAON, Changhuei YANG

Publication number: 20180292644Abstract: Metasurfaces comprise an array of meta-atoms in a stretchable polymer. The dimensions and shapes of the meta-atoms and the spacing are varied to obtain desired optical properties. Any optical wavefront, for different wavelengths, illumination angles, and polarization states can be designed with proper design of the meta-atoms. As the metasurface is stretched, the distance between the meta-atoms changes, modifying the optical response, while the dimensions of the meta-atoms remains constant.Type: ApplicationFiled: April 9, 2018Publication date: October 11, 2018Inventors: Seyedeh Mahsa KAMALI, Ehsan ARBABI, Amir ARBABI, Yu HORIE, Andrei FARAON
