Abstract: A novel tunable Electromagnetic Band-Gap, 2-D ferrite EBG, the performance of which can be adjusted by changing applied biased magnetic field, is proposed. The finite element method of the hybrid of edge-elements and node-elements incorporated with vector Floquet Theism is employed for calculating the scattering properties of this kind of EBG. Comparisons and Analysis of the frequency response of the transmitting power for this kind of ferrite EBG with different applied magnetic fields are presented, which shows better characteristic of stop and pass band-gaps,and more importantly the performance of the EBG devices is changeable by adjusting the biased magnetic filed. It indicates the possibility of R/D a novel performance tunable EBG.
