In this paper, a novel bi-layered chiral metamaterial (CMM) based design is proposed, which exhibits broadband operation of asymmetric transmission (AT) of linearly polarized waves. Simulation results of the proposed design shows wide-band AT response (transmission efficiency greater than 90%) in the microwave region from 8.48 to 10.16 GHz (1.68 GHz bandwidth) with a simultaneous cross-polarization conversion (CPC) response (conversion efficiency greater than 92%). The transmission and reflection response clearly indicate the AT and CPC results of our design. Both behaviors are explained in terms of cross-coupling between induced electric and magnetic dipoles due to surface currents. Finally, it is shown that AT response of the proposed design is stable with respect to variations in incident angle of the incoming wave up to 45. Due to its high efficiency, lowprofile, broadband response, and angular stability this design has numerous applications in modern telecommunication systems.
