Paper Abstract

To get two-dimensional (2-D) complete bandgap, a square lattice with complex crystal cell and a rectangular lattice with dielectric cylinders in air were investigated using plane wave expansion method. Their band structures were found to be different from those of an exact square lattice and they both can be implemented 2D compelte bandgaps. The rectangular lattice has compete 2D bandgaps when the ratio of the two bases is chosen properly.
