RF powder particles including an inductance element, a capacitance element, and a photovoltaic cell and method for exciting RF powder |
摘要 |
RF particles that can render more difficult fabrication of counterfeit notes and the like, can generate radiofrequency magnetic fields by oscillation of a tank circuit having a particular resonant frequency, and that can easily and reliably supply electric power for oscillation, RF powder, and a method for exciting the RF powder are provided. In an RF powder particle, a coil (inductance element) serving as an antenna and a capacitor (capacitance element) connected to the coil are formed on an insulating film surface of a substrate. The inductance element and the capacitance element form a tank circuit, and a photovoltaic cell for supplying power to the tank circuit is disposed on the substrate. |
