A nonolithic microminiature inductor comprising a helical conductive path of deposited metal film immersed in a rectangular block of magnetic refractory material. The inductor has metal caps at each end of the block as terminations. These terminations may be soldered to metallized pads located on a substrate. A method for making this inductor wherein loops of conductive metal are deposited onto a thin unsintered magnetically permeable ceramic sheet with holes for interconnection therein and wherein said holes are alligned and said sheets are laminated such that upon sintering said metal forms a helical contiguous conductive path immersed a contiguous block of ceramic.
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.
