چکیده :

In this paper, a plasmonic absorber with three dimensional (3D) double triangle-shaped (DT) nanoparticles is proposed and analysis. The absorbance value and bandwidth of the output spectrum in designed plasmonic absorber are 100% and 145nm, respectively. Size of the nanoparticles is investigated to optimize and tune the absorbance spectrum. The output spectra are stable for the wide incident angle in the range of 0°−40°. Therefore, the designed plasmonic absorber shows wide-angle absorption which is a key factor in designing of absorbers. This perfect absorber can also be used as sensors and filters due to its good characteristics such as broadband optical response, working in wide range of incident angles, and more significantly, nanoscale footprint of 300nm × 200nm × 40nm
