Abstract
A dual-band device has been designed and simulated to simultaneously detect optical radiation in the far infrared (at 10 μm) and the visible band. The infrared detector consists of a spiral antenna obtained from an adaptation of a Fresnel zone plate. Symmetric and asymmetric designs have been proposed and simulated. The response in the infrared is obtained from a computational electromagnetic calculation. The diffraction pattern at the focal point of the element has been calculated to check the feasibility of the modified design.
