Electromagnetic and Ultrasonic Nondestructive Evaluation (NDE)

Electromagnetic NDE

  • Efficient modeling tools for NDE applications using eddy current to calculate the changes in field distributions and impedances due to cracks and flaws
  • Semi-analytical solutions with truncated region eigenfunction expansion (TREE)

Ultrasonic NDE

  • Efficient simulation tools for general 3D arbitrary shaped flaws using ultrasonic wave
  • Accelerating computations using multilevel fast multipole algorithm (MLFMA)

Computational Electromagnetics

  • Efficient algorithms for wave propagation and interactions with materials for scattering and radiation problems
  • Fast integral equation solvers such as fast multipole method (FMM), adaptive cross approximation (ACA), etc.

Metamaterials for Antenna Applications

  • Model and design metamaterials and metasurfaces to increase antenna performances
