title: Calculations of two-dimensional electric field and potential distributions aroun electrodes in conducting media.
abstract: 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.
