摘要

The reflection spectra in one dimensional deformed quasiperiodic structure in high frequencies that cover the Global System for Mobile communication (GSM) bands, are studied using a theoretical model based on Abeles method for any geometry incidence, and both parallel (P) and serial (S) polarisations. We show that the transmission of electromagnetic waves is forbidden in this frequency band (photonic band gap) if the incident angle is lowest. The material systems used for the numerical analysis are Air/Ceramic and Air/Roger. This Photonic Band Gap (PBG) is also obtained for lower generations of deformed Fibonacci multilayer structure by increasing the deformation degree. An omnidirectional high reflector is obtained, it can coverall the GSM bandwidths by varying the refractive index of layers which compose the deformed Fibonacci sequence.
