Design of Huygens cells for transmit-reflect-arrays at 30 GHz

Résumé

In this paper, it is demonstrated that Huygens metasurfaces can achieve equi-amplitude reflected and transmitted waves and arbitrary phase shift in transmission, when illuminated by a normal plane wave. To exploit this property, a procedure for designing unit-cells of transmit-reflect-arrays is presented. First, the optimal surface parameters are analytically determined. Next, the design at 30 GHz of four cells with three patterned layers, compatible with printed circuit board technology, is presented. These cells operate with a maximum phase error of a 10° over a 5% relative bandwidth at the operating frequency, thus realizing a uniform 2-bit phase quantization in transmission and reflection.
