RF Tools

MATLAB software for calculating conductivity and permittivity of biological tissues.

We are sharing a collection of MATLAB applications for determining electrical properties of saline and tissues in radio-frequency (RF) field simulations.

RF Tools software interpolates the conductivity and permittivity of biological tissues and saline from experimentally measured data.

The algorithm uses experimentally measured tissue properties and published 4-Cole-Cole fits. In many instances, the measured data and the fits are not in good agreement, and thus we have included both to aid users in making informed decisions. RF Tools provides conductivity and permittivity of 45 different biological tissues ranging in the field strengths from 10Hz to 20GHz.
