1. A downhole drilling system, comprising:
a drill bit including a first electrode and a second electrode;
a pulse-generating circuit coupled to the first electrode and the second electrode; and
a capacitor within the pulse-generating circuit, the capacitor comprising:
a plurality of electrode sheets;
a plurality of dielectric sheets interleaved with the plurality of electrode sheets, each of the dielectric sheets comprising a composite material including a polymer matrix formed from a polymer component and a nanoparticle component that increases the dielectric constant of the composite material above that of the polymer component; and
a dielectric encapsulant that fills space between the interleaved dielectric sheets and electrode sheets.
