## Abstract In this article, an approach is proposed to provide an accurate and fast calculation on the transmission coefficients of an electromagnetic band‐gap (EBG) structures where patches are periodically inserted into the microstrip line (capacitive loaded EBG microstrip structure). The stopba

✦ Synopsis
We present here a program which will calculate either the photonic band structure or the transmission and reflection coefficients of photons incident on some complex metallic or dielectric structure. The method we use is to discretise the differential form of Maxwell's equations and arrange them such that we can apply the tried and trusted transfer matrix technique, often employed in condensed matter physics for calculating electronic properties of solids. The method is sufficiently general that any system with a well-defined unit cell can be studied.

## Abstract Two novel low‐pass filters (LPFs) of wide stop‐band are proposed in this paper. One filter is implemented by a photonic band‐gap (PBG) microstrip structure with T‐junction opened stubs and its frequency characteristics are discussed. The other filter is implemented by a PBG microstrip s
## Abstract Planar photonic bandgap structures have been modeled using the theory of transmission lines and periodic circuits. The method allows for fast and accurate computation of the dispersion diagram, and thus prediction of the stopbands for two directions of propagation. Results obtained by t
A new program has recently been implemented with the aim of extending quasi-particle (QP) band structure calculations to polymers with larger unit cells. The theoretical background is briefly reviewed and the new algorithm described, which has been optimized for machines with vector processors. To i
