Abstract: Exact solutions for a number of spatially non-uniform profiles of surface resistance, current and heat flux density distribution of Joule losses in metal-film capacitor structures are considered. The ratio of the total power losses for different profiles indicates a significant (2–3 times) decrease in the total heat release power in the case of using sharply decreasing distributions. The obtained effect is very useful in creating modern metal-film capacitors for efficient capacitive energy storage devices.

Keywords: metal-film capacitor, nanometer thick electrodes, surface resistance, Joule losses.
