Abstract
The transmittance of an evanescent wave generated from a prism coated with a double-layer thin-film structure is optimized with respect to various physical parameters including the incident angle, the refractive index and the thickness of the layers, and the illumination wavelength. A prism coated with an optimized double-layer stack produces an enhanced evanescent wave with a transmittance of 963, which is 17% higher than the reported result.
