Rice University scientists and collaborators have created a new type of two-dimensional (2D) semiconductor that comes closer ...

Abstract: This paper developed a photonically actuated ultrawideband, two-dimensional transmit array using a Fourier optical lens as a beamformer. Data encoding was developed, in which custom IF ...

Abstract: Large-scanned antenna arrays need to be periodically calibrated to correct for errors in excitation amplitude and phase, which degrade performance. The ability to adjust complex excitations ...
