Abstract: This communication presents a novel systematic design of a high-aperture-efficiency and 2-D beam-scanning nematic liquid-crystal (LC)-based reflectarray (LCRA) that operates in the ...

The model, called SHARP, can reconstruct a photorealistic 3D scene from a single image in under a second. Here are some examples.

Abstract: 2-Dimensional fast Fourier transform (FFT) has been widely used in radar signal process. Due to the need for high performance, field programmable gate array (FPGA) is an ideal hardware ...

Winter comes amply sprinkled in snow and aesthetic references—and the best winter nail designs embody them all. “Whenever winter rolls around, I always think of deep colors, and also metallics,” says ...
