Abstract:
1. An RF powder particle comprising an inductance element serving as a magnetic field coupling element and a capacitance element connected to both ends of the inductance element on an insulating surface of a substrate, wherein the inductance element and the capacitance element form a tank circuit, wherein the RF particle is physically bounded by an external surface, and wherein the RF powder particle is sized and shaped such that the external surface has a surface area of at most 0.3 millimeters squared; and wherein an insulating layer is formed on a side of the inductance element, wherein the capacitance element comprises a first electrode, a dielectric film, and a second electrode, wherein the first electrode is disposed between the dielectric film and the insulating surface of the substrate, and wherein the dielectric film is disposed between the first electrode and the second electrode and over the insulating layer.
