  1. Quantification of the electric field strength (E) for in-homogeneous models with needle electrode configurations which are defined in Fig. 2a-c. Conductivity of the target tissue is σtt = 0.4 S/m and the conductivity of the surrounding tissue σst = 0.2 S/m. Calculated minimal E (Ett min ) and maximal E (Ett max ) inside the target tissue and maximal E within the entire tissue E max for different needle electrode configurations. The results for models shown in Figs. 6a-6c were calculated for applied voltage U = 1 V ( d = 5 3  mm MathType@MTEF@5@5@+=feaafiart1ev1aaatCvAUfKttLearuWrP9MDH5MBPbIqV92AaeXatLxBI9gBaebbnrfifHhDYfgasaacH8akY=wiFfYdH8Gipec8Eeeu0xXdbba9frFj0=OqFfea0dXdd9vqai=hGuQ8kuc9pgc9s8qqaq=dirpe0xb9q8qiLsFr0=vr0=vr0dc8meaabaqaciaacaGaaeqabaqabeGadaaakeaacqWGKbazcqGH9aqpcqaI1aqndaGcaaqaaiabiodaZaWcbeaakiabbccaGiabb2gaTjabb2gaTbaa@349D@ ). Furthermore, by scaling the results we also calculated the parameters Ett min , Ett max and E max for U/d = 1300 V/cm.
