Advances in MMIC and RFIC technologies are driving 5G/6G and satellite communications with multi-band support, digital beamforming, and emerging sub-THz frequencies, while addressing key challenges in ...

A novel frequency diverse array (FDA)-assisted secure transmission framework is proposed, which leverages additional frequency offsets to enhance physical layer security. Specifically, an FDA-assisted ...

The construction of time-invariant spatial-focusing beampatterns using frequency diverse arrays (FDAs) has received significant attention in recent years for secure communications. This paper ...
