Classification: CPC H | IPC H

Claim 12:
13. A method for assembling a printed circuit board assembly (PCBA) device, the method comprising:
attaching a first dielectric layer to a first conductive layer;
attaching a second conductive layer to the first dielectric layer, wherein an electrical current is impressed on the second conductive layer when the PCBA is exposed to an externally generated electric field exterior to the PCBA;
attaching a trans-conductor layer (TCL) to the second conductive layer, the TCL including a plurality of TCL islands of a nickel-metal composite metamaterial, each of the TCL islands having a distinct shape providing a respective impedance value in response to a variation in an intensity and/or a wavelength of the externally generated electric field;
attaching a second dielectric layer to the TCL such that the TCL is positioned between the second dielectric layer and the second conductive layer; and
attaching a pre-pregnated layer to an inside surface of the first dielectric layer, wherein the first dielectric layer is attached to an inside surface of the first conductive layer, the second conductive layer is attached to an inside surface of the pre-pregnated layer, the TCL is attached to an inside surface of the second conductive layer, and the second dielectric layer is attached to an inside surface of the TCL,
wherein the TCL has a surface roughness configured to change in response to an energy level of the externally generated electric field to thereby change an effective permittivity of the second dielectric layer and thereby direct the impressed electrical current away from the second conductive layer.
