Three-dimensional RF electric fields in biological media and resistive materials.

Description | More information | Demos | Pricing | Sectors | Platforms

RFE3 calculates RF electric fields in resistive media. The program employs 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. In additional to standard 2D/3D plots, RFE3View generates 3D surfaces of constant potential, field amplitude or resistive power density. RFE3 has application to areas such as industrial RF treatments, geological measurements and biomedical procedures. (The mathematical methods of RFE3 apply at frequencies where the RF wavelength is larger than the simulated structure. Available for Windows or Linux. Requires MetaMesh)
