Color Filter Based on A Sub-wavelength Metal Grating
Abstract: This paper summarized the concept of periodic structure light filter, nature and experimental progress of manufacturing and processing，A color filter incorporating a sub-wavelength patterned grating in a metal film perforated with a square array of circular apertures on a quartz substrate was introduced. We take the COMSOL software simulation method to study transmission spectrum and the reflection spectrum of the periodic structure and put forward a kind of periodic structure light filter scheme to gain different structural parameters and filtering characteristics of different materials and quality factor.
Keywords: sub-wavelength metal grating, color filter, transmission spectrum, reflection spectrum
