摘要

Using the transfer matrix method (TMM), we study the transmission properties in Octonacci one-dimensional linear graded photonic crystals compressing a dielectric material and a magnetized cold plasma material. We found that the frequency and the quality factor of filters can be easily manipulated by tuning the external magnetic field (B). In addition, a linear gradation of the thickness allows to enhance the filter's performance, such as the optimization of the system sensitivity and the increasing of the filtering quality factor. Finally, this study ends by discussing the influences which come from the incident angle for both transverse electric (TE) and transverse magnetic (TM). All of these above parameters are optimized to obtain a tunable filter with high quality factor. These filters may be of interest to design satellite transponders and weather radars.
