From: Temperature-Controlled Asymmetric Transmission of Electromagnetic Waves
Metamaterial structure and simulated electromagnetic properties at room temperature. (a) Schematic of the unit cell exhibiting asymmetric transmission of linearly polarized waves, with parameters g = 5 μm, w = 8 μm, l = 49 μm, d = 11 μm, h = 500 μm and P = 82 μm. (b) Co- and cross-polarized spectral response |Txx|, |Tyx|, |Txy|, and |Tyy| of the metamaterial, where Tij represents the transmission coefficient describing i-polarized transmitted waves resulting from j-polarized illumination of the metamaterial’s front. (c) Asymmetric transmission for linearly and circularly polarized incident waves, where ‘−’ and ‘+’ correspond to left- and right-handed circularly polarized waves. (d) Polarization ellipse of the transmitted wave at 1.1 THz for x-polarized illumination of the metamaterial’s front.
