Abstract
AbstractIn this Letter a new analysis of an optical filter using a metallic photonic bandgap material on the microscopic scale is reported. The proposed filter is capable of working over a wide range of the electromagnetic spectrum and the idea is based on the famous Kronig–Penny model in the solid state. The periodic structure consisting of different conducting materials and dielectrics (air) are considered. The structure is also able to pass the light emitted by a He–Ne laser source by choosing the appropriate values of the controlling parameters, and thus this may act as an efficient monochromator. © 2002 Wiley Periodicals, Inc.
