An Ultra-Low Profile Metasurface for Enhanced Non-Diffractive OAM Beam Generation Based on Sparse Feed Array
Jinyang Bi, Fan Qin, Chao Gu +2
This paper proposes a novel ultra-low profile transmitted metasurface to generate enhanced non-diffractive orbital angular momentum (OAM) beams, employing a sparse feed array (SFA)…
Robust Beamforming for Magnetic Induction Based Underground Emergency Communications
Jianyu Wang, Tianrui Hou, Wenchi Cheng +1
Magnetic induction (MI) communication is an effective underground emergency communication technique after disasters such as landslides, mine collapses, and earthquakes, due to its…
