(a) Schematics of the realistically designed PB meta-coupler illuminated by the LCP or CP waves, producing high-efficiency chirality-controlled SPPs. (b) Sample picture and experimental setup to demonstrate the SPP excitation performance of the proposed PB meta-coupler. (c)(d) near-field measured and FEM simulated Ez field distributions (real part) above PB meta-coupler at 10 GHz, respectively. All figures are reproduced from [20].
