Dual Polarized Metasurface Based Absorber for Sub Millimetric / THz Applications

A metasurface absorber is designed in the THz band in order to investigate the field polarization. the conventional SRR and the proposed structure are investigated, firstly by applying X-polarized electric field on both cells and secondly applying Y -polarized electric field on both cells. as a result the conventional SRR reflects the incident electric field when the electric field is X-polarized and absorb when the electric field is Y -polarized. in case of the proposed structure is checked, it absorbs the incident wave in both directions of electric field polarization and the absorption is enhanced greater than the conventional one.
