Electromagnetic phenomena are used in wireless transmission, sensing and imaging technologies such as radar, subsurface sensing, MRI, microwave & induction heating, and in electrical components such as transformers. Electromagnetic interference and compatibility are big issues in design which can be resolved efficiently using simulations.
We have expertise in modeling of RF couplings, EM wave guides,
electrostatics, electrical circuits, EM modes in anisotropic dielectrics
and more. We use FEM methods as well as ODE based methods using commercially
available tools and also our own solvers.
CIRCUIT SIMULATION WITH EM COMPONENTS. A new methodology was developed to convert the PDEs governing linear electromagnetic components to ODEs, for fast and accurate simulation of EM components as electronic circuit components.
ELECTROMAGNETIC FEM. Built our own FEM EM solver to cross-check Mie scattering calculations, and to be able to perform scattering calculations for irregular shaped objects.
EM MODES OF A WAVE GUIDE. EM modes of a wave guide were calculated using a ray tracing (instead of PDE) method. The rays are not energy rays, as used in geometric optics, but “wave” rays, like Huygens/Fermat light theory (or like Feynman's histories).
