FIG. 12.

(a) Model geometry. (b) Exemplary electric field distribution. (c) Exemplary heat map due to Joule heating; the ambient temperature is assumed to be 20 °C. The cross section is taken perpendicular to the electrode edges and at the cell equator. The simulation parameters are $a_0=7.5\mu \mathrm{m},V_{pp}=50\mathrm{V}$, and $f=5\mathrm{M}\mathrm{H}\mathrm{z}$.
