Fig. 1. Conceptual illustration of the proposed low-profile self-stealth programmable metasurface. The metasurface exhibits radiation and stealth characteristics in the in-band co-polarization. It ...
The metasurface achieves two-dimensional beam scanning of ±45° at 5.2 GHz with a peak gain of 17.23 dBi while reducing radar visibility across five frequency bands. At 0.065 wavelengths thick, the ...
