RF Tools

RFtools is a group of MATLAB applications developed for determining electrical properties of tissues and saline for RF field simulations.

The current version can interpolate the conductivity and permittivity of (i) biological tissues and (ii) saline from experimentally measured data [1, 2], as well as use published 4-Cole-Cole fits to the experimentally measured tissue properties [1]. In many instances, the measured data and the fits are not in good agreement, and thus we have included both to aid the user in making informed decisions. You can obtain conductivity and permittivity of 45 different biological tissues ranging in the field strengths from 10Hz to 20GHz.


After downloading the zip file, unzip to a folder, then add the folder to the MATLAB paths using the MATLAB menu "File>Set Path>Add Folder". Type "RFtools" in the MATLAB command line to launch the application.


RFtools was developed using MATLAB 2007b. Compatibility was checked on the MATLAB 2006b platform. Older versions of MATLAB were not tested, but may function except for the "print to printer" and "print to PDF" functions.
