Abstract

In a letter by Yang (Microwave Opt Technol Lett 50 (2008), 2965–2967), the bandgap characteristic of a new uniplanar compact electromagnetic bandgap is considered. The authors use the dispersion diagram related to the irreducible Brillouin zone (IBZ) to determine the bandgap. We have already noticed the IBZ used by the letter is not correct, according to the symmetry of the structure. So, the resulted bandgap characteristic is not true. © 2011 Wiley Periodicals, Inc.

## Abstract The bandgap characteristics of several electromagnetic bandgap (EBG) structures are compared, and parametric studies of a wideband uniplanar compact photonic bandgap (UC‐PBG) structure are carried out. It has been presented that the bandgap bandwidth of the mushroom type EBG structure i

Several unique advantages of the Le Verrier-Fadeev-Frame method for the characteristic polynomials of graphs over the method proposed by Zivkovic recently based on the Givens-Householder method are described. It is shown that the Givens-Householder method proposed by Zivkovic, by itself fails for di

When the center frequency of a microwa¨e pulse is tuned ( ) across the spectral range of a photonic bandgap PBG structure implemented in microstrip technology, the group delay introduced ¨aries widely from high ¨alues to strikingly small ¨alues that gi¨e rise to superluminal propagation effects. In
