Abstract

We proposed and designed angle insensitive color filter based in metal/dielectric multilayers structures for red electromagnetic radiation (620-750nm). The thickness of the dielectric in the structure is calculated according to the physical theory and the omnidirectional resonance occurs when the reflection phase shift cancels the propagation displacement. The thickness of the metal is chosen analyzing a transmission properties in an interval of thicknesses previously described in the literature. We obtain analytically a highly stable filter with a transmission peak greater than 70% in approximately 634nm. This device can keep the same perceived transmitted color when the incidence angle changes from 0° to 50°, especially for TM polarized light.
