| Abstract: | Metasurfaces are two-dimensional (2D), or quasi 2D structures that offer precise manipulation of electromagnetic waves in terms of their amplitudes, phases, and polarization. All-Dielectric Metasurfaces (ADMs) allow for high electromagnetic wave transmission, minimal energy losses, and seamless integration with current semiconductor technologies. In this work, a chiral ADM that is based on silicon (Si) U-shaped resonators is presented. Numerical simulations demonstrate a broadband efficient Asymmetric Transmission of incident linear electromagnetic waves (1.07 to 1.28 µm) with 18.03% fractional bandwidth. The performance is explained via eigenmode analysis and the associated field profiles of the structure's eigenmodes. Moreover, the effects of different geometrical parameters are investigated providing insights for further optimization of the performance. [ABSTRACT FROM AUTHOR] |
