Electromagnetic and Numerical Modeling

  • Eigenvalue problems (cavities, waveguides)
  • Driven frequency-domain problems (generalized multi-port systems)
  • Driven time-domain problems (non-linearities)
  • Nearfield-to-farfield transformation techniques

Finite Element Methods (FE)

  • Fast solution techniques (domain decomposition, generalized multi-grid)

  • Error estimation and adaptive methods

Boundary Element Methods (BE)

  • Fast solution techniques (fast multiple multipoles, H matrices)

Model Order Reduction (MOR)

  • Fast frequency sweeps (dispersive and large-scale systems, large number of inputs/outputs)
  • Parametric MOR (non-affine parameters, domain decomposition)
  • Non-linear systems (quadratic-linear models)

Numerical Optimization

  • Parametric MOR-based solution techniques
  • Robust optimization
  • Application-specific modeling (antennas, filters, electrical machines)
