Calculations of two-dimensional electric field and potential distributions aroun electrodes in conducting media.
Tumor cells can be killed by heating to 42.5degreesC. It is convenient to localize heating by passing electric current at 500 kHz through tissue between a pair of electrodes. It is desirable to determine, for a given electrode-tissue configuration, what the resulting field and, therefore, current distribution will be. A computer program FFEARS was used to calculate electric field and potential distributions in two dimensions for three simple cases.
