A plasma photonic crystal (PPC) was formed using an array of discharge tubes. The transmission spectra and bandstructure PPCs with different lattice types under polarization modes were studied through simulation measurement. To study the bandgap in PPCs, PPC is calculated symplectic finite difference time domain (SFDTD), a modified plane wave expansion (PWE) method, element method (FEM) based on weak form equations. compared curve results. results show that stable PPC, experimental numerical agree well. There are PPC; TE-like caused by localized surface plasmon (LSP) Bragg scattering. TM-like cutoff effect electromagnetic type also affects position number bandgap. three methods have their advantages disadvantages when calculating bandstructure. Therefore, it necessary to combine accurately determine PPC.
