Latest Patents
Dinghao Yu holds a patent for a "Multi-mode surface-wave free-field inversion method based on dispersion properties of layered media." This invention tackles the inaccuracies found in traditional methods that often overlook higher modes. Yu's novel approach introduces a method for characterizing the participation quantity of each mode based on energy flux density. This technique is utilized to calculate a modal participation factor through dispersion curves and the frequency-domain dynamic stiffness matrix. The method further involves transferring ground surface-wave components with dispersion properties from the time domain to the frequency domain, where they are decomposed into harmonic components using Fast Fourier Transform technology. These components are then decoupled into multiple modes, allowing for the inversion of each single-mode component to construct single-mode surface-wave free fields. Ultimately, all single-mode surface-wave free fields are superimposed according to the mode superposition principle to create multi-mode surface-wave free fields.
