AC Currents in the live tissue with one needle electrode

QuickField simulation example

This is an example simulation, used by Professor Bertill Persson in preparation of his publication QuickField modelling of electro-pulse-therapy.

Problem Type
Plane-parallel problem of AC Conduction.

Geometry

Given
Electrical conductivity of the tissue is g = 0.35 S/m
Relative electrical permittivity of the tissue is ε = 9500
Frequency f = 60 kHz.
Voltage source U~ = 1 kV (peak), shield is grounded.

Task
Obtain the electric field distribution around the electrode.

Results
Electric field strength RMS magnitude color map
