Figure 1From: Analytical and numerical solutions of the potential and electric field generated by different electrode arrays in a tumor tissue under electrotherapy Electrodes configurations. (a) Conic sections: ellipse (e < 1), parabola (e = 1) and hyperbola (e > 1). (b) Electrodes array with shape of circle (I), ellipse (II), parabola (III) and hyperbola (IV). F, D, a, d, m, rn and θn are defined in the text (see Method section).Back to article page
