Abstract :
The numerical solution of Poisson´s equation, which describes the dielectric and/or conductive properties of biological tissue, is presented. Only two-dimensional problems are demonstrated; the third dimension is considered to be of unit length, with no boundaries at the two ends. The finite-element approach can handle any kind of nonisotropy and has the advantage that electrodes can be placed anywhere with very slight changes in the computer program. Further applications of the method are considered
