Abstract

The size of absolute band gap s in photonic crystals can be increased by reducing the lattice symmetry. Using this methods design the model of Photonic Crystals with heterostructure. In this paper a new structure by adding different rods into the unit cell of square lattices is explored, and we also consider the structure which overlays the glide symmetry lattice structure with single rod square lattice. Its band gap was calculated by the finite difference time domain method. Numerical analysis shows that the size of absolute band gap is enlarged in this way.
