Abstract: As a physical layer security technology, directional modulation (DM) can be combined with intelligent reflect-ing surface (IRS) to improve the security of drone communications. In this paper ...
Abstract: Metasurfaces can alter radar echo characteristics by dynamically modulating the phase of incident electromagnetic waves, thereby degrading radar signal processing performance. Recovering the ...
