Abstract
In this study, we numerically calculated the thermal radiative properties from the spoof surface plasmon mode on the Surface Modified Micro-Particle Array. The rigorous coupled wave analysis (RCWA) was used in the calculations. Au thin films in the shape of the surface of Micro-particle Array were made as the calculation models. The structural periods were 2μm, 3μm and 5μm. The calculated absorptance was enhanced in near-infrared in all models. The absorptance peaks of the calculate result were agreed with the analytical model results, and those were appeared in the wavelength vicinity to periodicities of the micro-structures. We conclude that the absorptance in near-infrared can be enhanced by Surface Modified Micro-particle Array.
