Broad-band heat reflector design using five-layer symmetrical periods from non-absorbing high-and low-refractive-index materials

摘要

Design of a heat-reflecting coating from two materials of high and low refractive indices is considered. It is realized using three-and five-layer symmetrical periods. Analytical study is performed to find the period structures and their arrangement in the multilayer. The final design is obtained numerically using a quality factor based on the visible transmittance and the infrared reflectance. Matching layers are added in order to improve the visible transmittance. [References: 19]
