Electromagnetic simulation plays a key role in designing products and investigating safety aspects for healthcare systems, which often include wireless telemetry.

Applications include wireless bio-sensors, implanted devices like pacemakers and neuro-stimulators, and MRI systems. Feko’s broad solver offering allows the most efficient method to be used for each task: MoM at early design stages with homogeneous phantoms; finite difference time domain (FDTD) or finite element method (FEM) for final analysis with anatomical phantoms. Use uniform theory of diffraction (UTD) and FEM for investigation of effects on large structures.

Key features:
  • Efficient simulation with the most suitable solvers and cross-validation strategies.
  • Spatial peak specific absorption rate (SAR) and other relevant post-processing performance parameters.
  • Free anatomical models available directly from Feko; other models available from various partners.
