Abstract: | Transverse magnetic (TM) and transverse electric (TE) defective bands will split with different incident angles (wave-vectors) in the one-dimensional coupled cavity waveguide. Different defective band properties are shown, including the shift of pass-band frequency and the variation of defective band width resulting from different localization properties of the electric field in the defective layer. The critical splitting angle, at which splitting of the TE and TM defective bands emerges, will decrease with increasing dielectric index of the defective layer. |
