M. Nenkov et T. Pencheva, SYMMETRICAL 5-LAYER PERIODS FROM NONABSORBING HIGH-REFRACTIVE-INDEX AND LOW-REFRACTIVE-INDEX MATERIALS, Journal of the Optical Society of America. A, Optics, image science,and vision., 14(3), 1997, pp. 686-692
Some properties of five-layer symmetrical periods from two nonabsorbin
g dielectric materials with high and low refractive indices are discus
sed. Conditions are derived for which two high-reflectance spectral re
gions (stop bands) are suppressed. Period structures with two successi
ve stop bands suppressed are proposed. The results are applied to the
initial design of a multilayer heat reflector with high visible transm
ittance, using only two materials. (C) 1997 Optical Society of America
