With a total of 2 patents, his work is paving the way for advancements in material characterization and analysis.
Latest Patents
Xian Li's latest patents focus on systems, apparatus, and methods of nonlinear terahertz (THz) magnetic resonance measurement. This innovative technique utilizes a sample illuminated by two THz pulses separately. The illumination generates two signals, Band B, corresponding to the first and second THz pulse, respectively, after interaction with the sample. The interaction includes the excitation of at least one ESR transition in the sample. Additionally, the sample is illuminated by the two THz pulses together, with an inter-pulse delay, generating a third signal B. A nonlinear signal BNL is then derived via B=B−B−B. This nonlinear signal can be processed, for example, through Fourier transform, to study the properties of the sample.
