Claim:
1. A composite material having a high dielectric constant greater than 20 and high dielectric strength of at least 1 MV/cm , the composite material comprising: a distribution of high dielectric constant ceramic particles dispersed in a polymeric material; the polymeric material, wherein the polymeric material is cured and bonds directly to the distribution of high dielectric constant ceramic particles; wherein the distribution of high dielectric constant ceramic particles is a trimodal distribution; and wherein a diameter of the ceramic particles of a largest diameter distribution of the trimodal distribution is between 40 μm and 220 μm.
