Optical devices require simultaneous control over wavefront and polarization of light to achieve various phenomena such as asymmetric transmission, reflection, and selective absorption. Traditionally, cascaded bulk components were used in these systems, which worked by manipulating the propagation phase of the incident light. These large components made the system impossible to miniaturize, which led to an interest in compact optical systems and the search for novel materials which would enable the system to exhibit the same phase-dictated phenomena through wavefront shaping. Here, we present a single-layered all-dielectric metasurface structure with nano-resonators which engineer the wavefront to achieve asymmetric transmission of circularly polarized light. A mathematical analysis of the phenomena is done using Jones Calculus. Finite Difference Time Domain (FDTD) Solutions is then used to optimize the structure hence achieving a 76% Asymmetric Transmission Parameter.
