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 2-D complete bandgaps. The rectangular lattice has complete 2-D bandgaps when the ratio of the two bases is chosen properly.
