Transmission spectrum of the third-order F-1D PhC for TE polarization state corresponding to fixed values of Fermi energy and period number as \({E}_{F}=80\)Â meV and \(N=4\), respectively, at incident angles (a) \({\theta=0}^{^\circ }\), (b) \(\theta ={45}^{^\circ }\), and (c) \(\theta ={80}^{^\circ }\).
