The concept of broadband extraordinary optical transmission (EOT) through metallic gratings at the plasmonic Brewster angle has recently been introduced. It is based on the ultrabroadband impedance matching between guided modes supported by ultranarrow slits in a one-dimensional (1D) metallic grating and an incident transverse magnetic (TM) wave. The overall mechanism results in total transmission through such a corrugated plasmonic screen. This concept was first demonstrated in 1D metallic gratings and it can also be extended to two-dimensional (2D) periodic metallic gratings made by either multiple rectangular or cylindrical rods. In this contribution, we review this concept and we demonstrate that this phenomenon can be applied to semiconductor gratings, whose materials have plasmonic properties at THz frequencies. This may open several opportunities to develop low-loss, broadband optical metamaterials for energy harvesting and concentrators.
