Abstract
A bilayer, ultrathin, dual-band chiral metasurface is designed and analyzed in this paper with linear polarization conversion and asymmetric transmission for Ku-band and 5G communications. The polarization conversion efficiency of the first band (11.8-13.5 GHz) is ultra-high having a value 0.95 at 12GHz and that of the second band (26.2-26.7 GHz) is 0.9 at 25.6 GHz. The proposed structure also exhibits linear polarization asymmetric transmission in both bands with asymmetric parameters above 90% and above 80% for the first and second bands, respectively. The structure is ultrathin with respect to lowest resonating frequency of 12 GHz having thickness of 0.032λ <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</inf> . Moreover, the structure is also angularly stable upto 60° for first band and upto 30° for second band, making the structure robust for practical applications. Due to scalability of the design, the proposed structure finds wide range of applications, covering a large spectrum from microwave to 5G bands.
