Description :-

In the current 1D FDTD simulation, to the left half is Air/Vacuum (Epsilonr=1)and the right half is a Material (Epsilonr=4). So the wavelength of sinusoidal signal, pulse width and propagation velocity of the Gaussian Pulse changes in the left and right hand sides of the simulation domain, due to the difference in permittivities which translates to change in refractive index. Objective of the program is to solve for the Maxwell's equation for an x-directed z-polarized TEM wave containing the y-directed magnetic field Hy and z-directed electric field Ez, using 1D FDTD with effects of permittivity modeled.
