Abstract: It has been found that a sinusoidal electric field is enhanced by a factor of more than 10$^3$ in two plane-parallel layers of different dielectrics placed between plates of a parallel-plate capacitor. The implementation of the enhancement of the electric field requires that the following two conditions should be satisfied: (1) one of the two layers should consist of finely dispersed dielectric particles with ionized donor centers formed on their surface and free electrons in their bulk, and (2) the dielectric permittivity of the powder should have a negative value. It has also been found that, in the powder layer, the enhancement of the electric field occurs simultaneously with its inversion.
