    Abstract:
    In this paper， a multifunctional chiral metasurface is presented to achieve asymmetric transmission （AT） and linear-polarization conversion （LPC）. The designed metasurface consists of a cross swords-like shape and two holes in the lower side of the unit cell. In the frequency band from 8.3 GHz to 10.4 GHz， AT is realized with more than 90% efficiency and the same chiral metasurface transforms linear polarized wave into its orthogonal counterpart with high efficiency. For LPC， the polarization conversion ratio （PCR） is greater than 95%. The proposed metasurface is stable against the incident angles of striking electromagnetic （EM） waves up to 60° for both operations of AT and LPC.
