Abstract
The passband and stopband of symmetrical metal-dielectric films are calculated and considered in this work by analyzing the equivalent phase thickness through calculation of characteristic film matrix. The passband and stopband are reduced with decreasing wavelength. At extreme long wavelength ranges the metal-dielectric multilayer are transparent. Therefore the first stopband from infinite wavelength are derived here. This analysis can be applied to design for the passband and stopband of a layered metamaterial.
