Abstract: This article presents an improved approach for the synthesis of sparse planar arrays using the density-weighted method and chaos sparrow search algorithm (CSSA) with multiple constraints.

For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...
