Finite-difference time-domain (FDTD) simulation of electromagnetic propagation of a short ultrawideband pulse (central frequency 700 MHz) in random medium. The randomness is achieved via the randomly fluctuating of the dielectric permittivity of the environment. Such a scenario is encountered in ground penetrating radar applications (GPR) where the subsurface (soil) can be modeled as random media.
