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 ($d=5\sqrt{3}\text{ mm}$). Furthermore, by scaling the results we also calculated the parameters Ett_min, Ett_max and E_max for U/d = 1300 V/cm.
