WebThe system is composed of subwavelength H-shaped apertures with extended arms fabricated through thin metal films on a free-standing dielectric membranes. Through finite-difference time-domain calculations, we numerically investigate the multi-resonant spectral nature of the compact system in detail, which is associated with the individual optical … WebThe thin polymer films were spin coated from dilute solutions onto gold substrates. The effects of varying film thickness on the infrared spectra were investigated. Multiple-layered films were prepared by multiple spin-coats on gold-coated glass slides yielding polymer films with thicknesses between 1 to 7 micrometers as measured by profilometry.
