Light passing through subwavelength apertures
WebAnswer (1 of 3): Refraction of Light as it passes from more dense to less dense mediums. The bending of light as it passes from one medium to another is called refraction. The … Webthe first practical use of subwavelength apertures to enhance light-matter interaction dates back to 1986 [14]. In this study, apertures of diameters down to 180 nm fabricated in silver or gold films on glass slides were used as substrates to detect fluorescent molecules, and clear indications of fluorescence enhancement were reported.
