New cell-scale robots can sense their environment, compute decisions, and move independently without magnetic or ultrasonic control systems.

Abstract: Code hopping multiple access (CHMA) is an emerging technology to implement code domain non-orthogonal multiple access (NOMA). In CHMA, multiple access interference and multipath interference ...

Abstract: Polarimetric phased arrays (PPAs) enhance radar target detection and anti-jamming capabilities, but their conventional dual transmit/receive (T/R) channel architecture leads to high cost and ...
