Analysis of the characteristics of electromagnetic wave propagation in dielectric fiber bunched waveguide

Dielectric fiber bunched waveguide is a kind of cylindric dielectric waveguide array (CDWA). Based on the established theory for two-dimensionally periodic medium, electromagnetic wave propagation in cylindric dielectric waveguide array which was arrayedby a rectanglar array was calculated and analyzed. The characteristics of wave propagationin cylindric dielectric waveguide array were presented. Besides, these characteristics were compared with those of wave propagation in rectangle dielectric waveguide array. And the results are satisfying.
