Frequency band of 30 to 300 GHz, which is termed as mm wave band offers 100 times bandwidth as compared to sub 6 GHz band. In this study, we propose a novel design which acts as a near unity absorber at 258 GHz or 0.258 THz in Y polarization and 292 GHz or 0.292 THz in X polarization. The study also includes effect of change in parameters on resonance frequency in both X and Y polarization which allows us to use same design with modified parameters to get near unity absorptivity in frequency of 205 to 345 GHz. Further, we also discuss on higher frequency mode which particularly appears in Y polarization and on changing the inner square dimension of the design.
