Dielectric Surface Impedance Approximation

The dielectric surface impedance approximation is a solution method that can be applied to homogeneous, lossy dielectric regions. Use the solution method to compute SAR values for a homogeneous phantom.

Note: Restrictions apply when solving regions with the dielectric surface impedance approximation:
  • The region must be in free space (cannot be contained inside another region).
  • The region may not touch or intersect another region when the media properties differ.
  • The boundary surface must be a closed dielectric surface without any metal parts.
  • No sources may be located inside the dielectric region.
