RFE3 calculates RF electric fields in conductive dielectrics using high-accuracy finite-element methods for high-accuracy. The package includes RFE3View, an interactive analysis program to find spatial variations of the amplitude and phase of electric fields and current. RFE3 has application to areas such as industrial RF treatments, geological measurements and biothermal procedures.



  • Export power-density profiles to HeatWave for thermal analyses.

  • Define spatial variations of relative dielectric constant and electrical conductivity from mathematical functions.

  • New solution techniques resolve microscopic details in large structures.

  • Automatic surface integrals to calculate mutual capacitance, resistance and net current.

  • Interactive line scans and plots with digital oscilloscope features.

  • Define up to 256 material regions with specified conductivity and relative dielectric constant.

  • Batch-mode operation for automated analyses.

  • The voltage amplitude and phase of electrodes may be set individually.


RFE3 is a versatile numerical tool to find RF (radio-frequency) electric fields in conductive media for arbitrary three-dimensional geometries. The program applies finite-element methods on a conformal hexahedron mesh for high accuracy.  You can define up to 250 regions to represent electrodes or different materials. The amplitude and phase of the harmonic potentials on electrodes may be set individually. Conductive materials are characterized by values of the volume resistivity and relative dielectric constant. Material properties may be uniform over a region of the solution volume or may vary following user-specified mathematical functions.The program can export a power density file that may be used in the HeatWave program for thermal analysis. RFE3View, an interactive graphics analysis program, provides full information on the amplitude and phase of electric fields and current density throughout the solution region.


The package includes two programs:

  • RFE3.EXE- determines one or more solutions in a window or under batch file control

  • RFE3VIEW.EXE- generates plots and analyses of solutions fromRFE3.
