Abstract :
The formulation of the finite difference time domain method (FDTD) for the analysis of propagation characteristic of rectangular waveguides filled with magnetized plasma is presented here. In this formulation the FDTD method is used for the numerical solution of Maxwell´s equations in the time domain. As a result, the system of partial differential equations formed by the electric and magnetic field components is replaced by a system of finite difference equations that are solved iteratively. The results presented show a variation of the dispersion characteristics of the structures examined as functions of the plasma parameters
