Abstract :
In this paper, optimum design, numerical simulation and full-wave analysis of two broad-band metamaterial absorbers have been presented in the infrared, visible light, and ultraviolet frequencies of the sunlight spectrum. These planar absorbers consist of two conductive layers and an intermediate insulating layer. The simulations results obtained by the finite integration technique have shown that performance of the designed absorbers is independent of the incident wave polarization and its elevation and azimuth angles. The proposed absorbers have an absorption of more than 92% in the visible light range. Therefore, these absorbers can be used to harvest the energy of sunlight
