Dielectric Surface Impedance Approximation

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

Note: Restrictions apply when solving regions with the dielectric surface impedance approximation:
  • The region must be in free space.
  • A 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.
