Latest Patents

One of Zhi-Gang Yu's notable patents is for RFID tags having ferromagnetic patches. This invention utilizes ferromagnetic films to store information effectively. The RFID tags include patches of ferromagnetic materials, each with a specific ferromagnetic resonance frequency determined by the composition of the ferromagnetic film. When stimulated, these patches emit microwave or RF signals at their resonance frequencies, with intensities proportional to the patch sizes. The emitted signals can be read, and the frequency spectrum of the tag can be determined using a Fast Fourier Transform (FFT). This spectrum provides identity and other information.
