Propagation of terahertz waves through an inhomogeneous collisional magnetized plasma layer is studied. The plasma has bell-like electron density distributions, but collision frequency is constant. The transmission, reflection and absorption of s-polarized wave obliquely incident on the plasma slab, are found using the impedance matching method. Here the external magnetic field is uniform and its direction is perpendicular to inhomogeneity direction and parallel with the plasma surface. The effects of the incident wave characteristics, such as frequency of the electromagnetic wave and its incident angle, and plasma parameters, such as the inhomogeneity coefficient, cyclotron frequency and collision frequency on transmission, reflection and absorption are investigated.
