In order to study the effect of the structure of photonic crystal on electromagnetic wave transmission characteristics,a new 2-D hybrid photonic crystal structure was proposed.By means of finite difference time domain method,the optical transmission properties of 2-D hybrid photonic crystals were studied.Furthermore,it was also studied how the shape and structural parameters affect transmission properties of photonic crystal.The results show that the new structure not only maintain the primary band gap of the former structures but also produce a new band gap.Compared to the compound dielectric cylinder,the simple one has riot produced a new band gap.Both increasing the width of medium plate and the radius of embedded concentric circle arc in favor of the new band gap emerging.The theory basis of the design of photonic devices is provided.
