  We discuss different applications and potentials of reciprocal bianisotropic
metasurfaces including uniform and gradient metasurfaces, in particular, with
anisotropic, chiral, and omega properties. Based on an analytic analysis, we
discuss the necessary conditions to observe asymmetric co- and cross-
polarization reflection and/or transmission, polarization conversion and
rotation, asymmetric absorption, etc. We consider two kinds of incident wave
scenarios based on linear and circular polarization.
