Latest Patents

Yaozhong Cui holds a patent for a "Multi-mode surface-wave free-field inversion method based on dispersion properties of layered media." This method tackles the inaccuracies found in existing techniques that often overlook higher modes. By proposing a novel approach that characterizes the participation quantity of each mode based on energy flux density, he enhances the calculation of modal participation factors through dispersion curves and the frequency-domain dynamic stiffness matrix. The method involves transforming ground surface-wave components from the time domain to the frequency domain using Fast Fourier Transform technology. This allows for the decomposition into harmonic components, which are further decoupled into multiple modes. Ultimately, the single-mode surface-wave free fields are superimposed to create multi-mode surface-wave free fields.
