The dispersion characteristics of binary 1D-PPCs having inhomogeneous plasma in the unit cell are studied. Using the transfer matrix method the required dispersion relations are obtained. Here the linear and exponential plasma density profiles are considered and compared with the homogeneous plasma having uniform density profile. It is observed that the inhomogeneity in plasma layer highly affect dispersion curves. By comparing the dispersion curves obtained in all considered cases, it is found that the widths of band gaps and phase velocities are always larger for exponential density profile than the linear uniform density profiles in the considered frequency range.
