Wide-Angle Anomalous Refraction Using Efficient Surface Field Optimization for Different Polarizations
In this work, numerically efficient surface field optimizations for transverse electric (TE) and magnetic (TM) polarizations are presented to design locally lossless and passive metasurfaces (MTSs) performing anomalous refraction. The MTS consists of the cascade of three patterned metallic layers, modeled through homogenized impedance sheets. A certain number of evanescent Floquet modes are introduced through an optimization procedure aiming at minimizing the real part of the sheets surface impedance. Numerical results show a good agreement between the two cases for a near-perfect anomalous refraction without reflection considering arbitrary incidence and refraction angles.
