Buried Metallic Plates Current Scattered Field Distributions

This page shows results illustrating the current distributions on buried conducting plates and scattered-field distribution.

Dr. Tie Jun Cui's current research interests are in the forward and inverse scattering by objects buried underground, which more particularly include:

  • Fast evaluation of Sommerfeld integrals.
  • Efficient methods for EM scattering by buried objects of small and moderately size.
  • Fast algorithm for EM scattering by buried objects of large size using CG-FFT.

  • Currently, Dr. Cui is working on a project in collaboration with the US Geological Survey. Some related publications about this work are given in the following:
