Omni-directional high reflectors using one-dimensional deformed quasi-periodic cantor band gap structure at ultra high frequency band

By using a theoretical model based on Transfer Matrix Method (TMM) for any incidence simulator and for both parallel (P) and serial (S) polarisation, we study the reflection spectra of one-dimensional (1D) deformed quasi-periodic Cantor structures, at ultra high frequency band. It is obtained a broad Omni-directional reflection band covering a great part of UHF band which contains the Global System for Mobile communication (GSM) bands. The propagation of electromagnetic waves is forbidden in this region for all incident angle and all polarisations. Deformation was introduced by applying a power law, so that the coordinates y of the deformed object was determined through the coordinates x of the Cantor stack in accordance with the following rule y=x^k+1, where k: the coefficient defining the deformation degree.
