Ground Penetrating Radar (GPR) FDTD Animation

Finite-difference time-domain (FDTD) animation of a sample ground penetrating radar (GPR) in action. Basically, a transmitting antenna shoots a short electromagnetic pulse (with a central frequency of 600 MHz) into the subsurface where the relative dielectric permittivity is 4. The short pulse is reflected from the air-soil interface and then either the rectangular or circular targets embedded in the subsurface. Then, the scattered signals are recorded by the receiving antenna of the GPR unit. This constitutes a single A-scan for the GPR measurement. Collection of A-scans along a spatial range constitutes the so called B-scans. Depending on the reflectivity of the target and soil properties, the success of GPR detection varies.

Electromagnetic Propagation of UWB Short Pulse in Random Medium

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.
