Patent number: 10102974Abstract: Prismatic polymer monolithic capacitor structure including multiple interleaving radiation-cured polymer dielectric layers and metal layers. Method for fabrication of same. The chemical composition of polymer dielectric and the electrode resistivity parameters are chosen to maximize the capacitor self-healing properties and energy density, and to assure the stability of the capacitance and dissipation factor over the operating temperature range.
