Propagation of transients in tapered transmission lines with dispersive dielectric media and time-dependent load using FDTD method
A numerical method to solve the propagation of transient electromagnetic waves in dispersive dielectric media with time-dependent load using FDTD will be presented. The voltage and currents will be computed directly from the Maxwell equation in dispersive dielectric media. The effect of the time-dependent load will be considered as a time-dependent boundary condition. The results of this paper have application in wave propagation in biological media in which besides the dispersive media the boundary conditions may be time-dependent. Finally we give some examples of Gaussian and square pulse propagation in some dispersive tapered lines.
