| Abstract: | The model to analyze the band gap structure of arbitrary shape 2-D electromagnetic crystals was established based on plane wave expansion(PWE) method in this paper.The structure coefficients of electromagnetic crystals were solved by numerical discretization method,and the band gap structure was derived by intrinsic equation.The analysis results of square rods,complex lattice electromagnetic crystals and fractal electromagnetic crystals showed that the numerical results were well agreed with data in referen... |
