The second-order of approximation numerical method for solution of Maxwell Equations in nondispersive medium, called FDTD (Finite-Difference Time-Domain), also known as Yee algorithm, was used to create the software package for modelling of electromagnetic waves propagation in medium (with the Courant stability condition). The Total Field/Scattered Field (TFSF) source is considered in detail. Inhomogeneous medium is also included into the model and there are some examples, which show, how the program works with it. The different boundary conditions (periodic, reflecting and absorbing) were looked into. Perfectly Matched Layer (PML) absorbing boundary conditions are used in the program and the corresponding results are discussed. Different types of sources are realized in program, the results of the waves propagation are shown.
