Asymmetric transmission plays an important role in many electromagnetic systems. Different to the asymmetric transmissions in full space, angular-asymmetric transmissions support different characteristics for symmetrical oblique incidences in half space, which has great potentials for antenna designs and wireless systems. This communication designs and demonstrates a dual-band multi-functional metasurface with angular-asymmetric transmission and frequency selection under oblique incidences. At 8.7 GHz, the 30° incident TM wave is bounded in the metasurface, and the −30° incident TM wave transmits, which presents an angular-asymmetric transmission. At 10.4 GHz, both ±30° TM oblique incident waves can be transmitted, which presents a frequency selection function. The metasurface sample with optimized geometry parameters has been fabricated and measured, and the measurement results agree well with the simulation results.
