A two-dimensional model for electromagnetic wave propagation in a dusty plasma crystal is solved using plane wave expansion techniques. We show that photonic band gaps, where propagation is forbidden, can occur for a range of Debye length scale sizes with respect to the dust particle size. We find that band gap features are dependent on the plasma sheath characteristics of the dusty plasma crystal. In addition we compute the damping due to the conductivity of the dusty plasma crystal.
