The theory of the effective dielectric function of a nanocomposite dielectric disposed between the metallic electrodes in a capacitor is developed from first principles. Following the Maxwell Garnett approach, the spherical nanosized inclusions in the dielectric are modeled by point dipoles and the electromagnetic field of the induced dipoles reflected from the electrodes is taken into account using the dyadic Green’s
function. The developed theory substitutes the Maxwell Garnett approximation for nanocomposites in the subwavelength regime, which is realized in electrical engineering.
