Abstract
In 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.

## Abstract An antenna based on a three‐dimensional metallic photonic bandgap (MPBG) structure consisting of many parallel metallic short wires is considered. An explicit method is introduced to calculate the radiation pattern for such an antenna system. The explicit method is verified numerically
Using a linear periodic refracti¨e index pattern on the macroscopic scale in a suitable material, a new type of ultra¨iolet filter is suggested. This structure is able to act as an efficient ultra¨iolet monochromator.
