Electromagnetic Simulation and Design

Activity of the research group:

• Theory of electromagnetic fields (classical electrodynamics in engineering perspectives, including the relativistic theory).
• Teaching activity in the field of electromagnetics (at the faculties “VIK” and “GPK”), continuous development of the scope of the courses, and integration of the new scientific results in the education.
• Research in the field of development and implementation of numerical techniques (finite elements, finite differences (time domain), integral equations, finite integrals, ray tracing, etc.)
• Research in the field of inverse and optimization problems.
• Data-fit surrogate models (mesh-based, sparse grid, kriging), inversion, optimization, deterministic and stochastic approaches, sensitivity analysis (e.g., Sobol’ indices), machine learning, etc.
• Constitutive models, homogenization: magnetic materials, superconductors, artificial materials (frequency-selective surfaces, meta-materials).
• Research in the field of wave propagation and scattering problems.
• Participation in RDI projects in which the above competences can be applied:
  • nondestructive testing and evaluation (NDT&E)
  • wireless power transfer (WPT): capacitive and inductive (resonant) coupling
  • integrated optics, optical fibers (microbending loss)
  • superconducting coil design
  • wave propagation and scattering: deterministic and stochastic models, micro-Doppler effect
  • analysis and design of microwave devices: antennas, anechoic chamber, MRI RF coil
  • radiating near field: SAR prediction, validation of computational methods,
  • simulations related to driving assistant radars
  • finite element calculation (element by element method) on CUDA card

Recent results:

• Modeling of capacitive and inductive wireless power transfer for device design and optimization
• Modeling of Litz-wires for accurate calculation of ohmic loss
• Application of sensitivity analysis based on Sobol’ indices for electromagnetic models
• Antenna near field modeling and development of methods for validation of numerical simulations thereof
• Automotive EMC measurements: numerical model development
