ABSTRACT:
In one embodiment, a method for fabricating electromagnetic meta-materials includes applying first and second array of electromagnetically reactive patterns to first and second non-conducting surfaces, wherein the first array includes at least one of a split ring resonator pattern, a square split ring resonator pattern, and a swiss roll pattern, and the second array includes a thin parallel wire pattern. The first and second non-conducting surfaces are joined together such that the first and second non-conducting surfaces bearing the first and second arrays of electromagnetically reactive patterns are commonly oriented. Alternately, a method may further include slicing between elements of the first and second arrays of electromagnetically reactive patterns in a plane perpendicular to the first and second surfaces to form a plurality of slices, rotating at least one of the slices, and applying a third array of electromagnetically reactive patterns to a third non-conducting surface.
