Abstract: The metasurface can provide beam deflection by providing phase gradient. In this work, a single-layer small size transmission-type metasurface is used to generate a deflect beam in the ...

Abstract: In this letter, a 3-D Eaton lens with gradient refractive index (GRIN) distribution for beam deflection at X-band is designed, fabricated, and measured. The ideal 90° beam bending of Eaton ...
