Near Fields and SAR

Near fields and SAR data consist of values for the electric and magnetic field strength as well as specific absorbtion rate (SAR) data.

Electric Field Strength

The position as well as the individual components of the electric and the magnetic field strength are given. Unless otherwise requested in the request, the total value of the field, that is the sum of the incident wave and the scattered field, is given.

Note: In the above table the spacing between columns was reduced to facilitate convenient rendering of line breaks in the rows of data.

The magnetic field strength data will have very similar contents.

Electric Fields inside Dielectric Cuboids

If the electric fields inside dielectric cuboids are requested (Electric field and SAR values request in the FE card) then the value for the SAR and the cuboid number are also given as follows:

SAR

For specific SAR solution requests, the following output is shown (note that the extract shown below is representative for a spatial peak SAR calculation. The output for other options like volume average SAR calculations will differ.)
