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

In this paper, we have analyzed the guiding problem by dielectric waveguide with defects area composed of dielectric circular cylinder array loaded with deformed rhombic dielectric structure in the middle layer, and investigated the influence of the distribution of energy flow for defect area by using the propagation constants of the guided region. Numerical results are given for the complex propagation constants and distribution of enegy flow for case of comparison of both rhombic dielectric structure and deformed rhombic dielectric structures by using the combination of improved Fourier series expansion method and multilayer method. As numerical results, it is shown that we can be obtained the confinement efficiency by rhombic dielectric structure compared with defomed rhombic dielectric structures for TE and TM modes.
