A hybrid conductive material comprising at least one conductive material having at least one internal porous insulative layer; and wherein, at least one of the conductive materials fills the voids of the internal porous insulative layer. The hybrid material blends conductive metals and porous insulation layers in a manner so that the resulting material operates as a single layer material with its own unique conductivity and skin depth; and a unique and strong directional impedance. By using a porous insulation layer, metal layers may be bonded together through insulation layers, and this allows rapid low-cost formation of the hybrid material. The hybrid material may be used to form thin wires or traces capable of handling high frequency applications.
