Abstract

A recently published rectangular unit cell based finite difference time domain (FDTD) method used to calculate the energy bands of perfect two-dimensional (2D) photonic crystals (PTCs) with a hexagonal lattice, is further extended by the authors to the calculation of the energy bands of 2D phononic crystals (PNCs) with a hexagonal lattice. Numerical results show that accurate calculation of the energy bands of the perfect or defect-containing 2D PNCs with a hexagonal lattice can be given by using the rectangular unit cell or supercell based FDTD method.
