- Abstract
- In this paper, the properties of a Metallic Photonic Band Gap Prism (MPBGP) with defects are studied. The MPBGP is made of metallic rods disposed in an isosceles right-angled triangle. The commercial software HFSS based on the finite element method is used to study the behavior of Photonic Band Gap structure by means of three-dimensional dispersion diagrams, iso-frequency curves, radiation patterns and the cartography of electric field. Numerical results showed that the metallic photonic band gap without and with defects behaves like a homogeneous and ultrarefractive medium in the first allowed frequency band. The distribution of defects doesn't modify the propagation of electromagnetic waves through the metallic photonic band gap material, it has properties similar to that of a perfect prism. In the forbidden frequency bands, the anomalous transmission has been obtained by means of surface defects in Metallic structure. This anomalous transmission in forbidden band has also been observed in simulations carried out on a dielectric photonic band gap material made of dielectric rods disposed in an isosceles right-angled triangle. Theoretical results presented in this paper have been successfully validated by measurements carried out in the frequency range [7-16 GHz].
