A plain white envelope shows up in your mailbox. It is addressed to you. It may even have a tracking number. The sender's name looks unfamiliar, but the delivery seems real. Then you open it. Nothing ...

Abstract: Accurate modulation recognition and parameter extraction of overlapping low probability of intercept (LPI) radar signals in dense electromagnetic environments remain significant challenges.

Abstract: Motivated by the extraordinary modulation capability of the electromagnetic (EM) metasurface technique, a time-modulated metasurface-assisted moving target jamming method is proposed for the ...
