The effect of refractive index, rectangles length and the ratio of width to length of the rectangles on the PBG properties of the structure with different configura- tions was investigated. It is found that the density of gaps in both modes （transverse electric （TE） and transverse magnetic （TM）） is high for structure composed of rectangular dielectric rods in gaps is very low for structure pores in dielectric material. air, while the density of the composed of rectangular air展开更多
