Multi-layer magneto-dielectric material

A magneto-dielectric material operable between a minimum frequency and a maximum frequency, having: a plurality of layers that alternate between a dielectric material and a ferromagnetic material, lowermost and uppermost layers of the plurality of layers each being a dielectric material; each layer of the plurality of ferromagnetic material layers having a thickness equal to or greater than 1/15th a skin depth of the respective ferromagnetic material at the maximum frequency, and equal to or less than 1/5th the skin depth of the respective ferromagnetic material at the maximum frequency; each layer of the plurality of dielectric material layers having a thickness and a dielectric constant that provides a dielectric withstand voltage across the respective thickness of equal to or greater than 150 Volts peak and equal to or less than 1,500 Volts peak; and, the plurality of layers having an overall thickness equal to or less than one wavelength of the minimum frequency in the plurality of layers.
