Abstract
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.
