A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital spatial ...

Abstract: In this work, a metasurface lens (MSL) antenna based on transmission elements with independent control of amplitude and phase is proposed. The lens consists of a 12 × 12 array of ...

Abstract: In this paper, a novel orthogonal quad-beam scanning antenna using 1-bit dielectric modulation in a planar plasmonic metamaterial transmission line (PMTL) is proposed. The PMTL is realized ...
