Distribution of energy flow by dielectric waveguide with rhombic dielectric structure along a middle layer

[摘要] References(8)Cited-By(2)In this paper, we analyzed the guiding problem for dielectric waveguide introduced as defect layers composed of dielectric circular cylinders with rhombic dielectric structure along a middle layer, and investigate the distribution of energy flow of dielectric waveguides for both TM0 and TE0 modes by using the propagation constants at the guided area. From numerical results, we can be obtained the confinement efficiency by loaded with rhombic dielectric structure compared with dielectric triangular cylinders for TM0 mode. In the case of TE0 mode, it is shown obviously that we can be obtained the confinement efficiency loaded with dielectric circular cylinders compared with rhombic dielectric structure.
