Modeling of wave propagation of ordinary and extraordinary modes in magnetized inhomogeneous plasmas is a challenging problem especially if the plasma considered has irregularites whose size is comparable to the wavelength of the waves in consideration. If the density in the irregularities is such as to be overdense in some regions and underdense in other regions,the wave can undergo partial reflection and tunnelling as well as direct propagation through this complex dielectric. Since the simulations are conducted in finite boxes, the tunnelled wave as well as the transmitted waves should propagate through the finite boundaries without any reflection. This is important to get a realistic distribution of the wave pattern as well as magnitude of the wave amplitude especially at mode-conversion points. We have develepoed a 2D full-wave propagation code which models this by implementing perfectly matched layers at the side and top boundary for electromagnetic waves launched vertically at the lower boundary of the box. These perfectly matched boundary layers prevent reflection of the wave from the side and top boundaries of the computational box. We will present wave patterns and mode-conversion effects for a variety of plasma irregularities which for instance can occur during the sporadic E phenomenon.
