摘要

本文研究了一维磁星形波导结构(MSWG)的反射特性和波阻抗在光子带隙形成中的作用。通过对色散特性的分析，发现磁性光子晶体(SWG)结构中带隙的存在不需要组成材料波阻抗的对比，而普通磁性光子晶体(MPC)结构中带隙的存在则需要组成材料波阻抗的对比。此外，在相同的波阻抗对比度下，磁性SWG结构比普通磁性PC结构具有更宽的光子带隙。

Role of wave impedance in the formation of photonic band gaps in one-dimensional magnetic star wave guide structure

The present paper describes the study of reflection properties and role of wave impedance in the formation of photonic band gaps in one-dimensional magnetic star waveguide structure (MSWG). From the analysis of the dispersion characteristics, it is found that in magnetic SWG structure existence of band gaps does not require the contrast in the wave impedance of the constituent materials whereas the contrast in wave impedance is must for the existence of band gap in normal magnetic photonic crystal (MPC) structure. Moreover, magnetic SWG structures show wider photonic band gaps in comparison to normal magnetic PC structure for the same contrast in the wave impedance.
