Design of dual-band perfect absorber
Opto-Electronics and Communications Conference（2015）
摘要
A plasmonic structure is proposed to achieve perfect absorber. Numerical simulations indicate that there are two absorption peaks at wavelength 1565nm and 1998nm with absorptivity 99.93% and 99.86%, respectively. Near perfect dual-band absorber is obtained.
