Latest Patents

Chun Guang Piao holds a patent for "Ultrasonic transducers for flow velocity measurement with meta slab." This invention features an ultrasonic transducer that employs a meta slab, which includes a piezoelectric body designed to generate elastic waves. The meta slab is connected to the piezoelectric body and is configured to induce elastic wave mode conversion resonance with respect to the elastic waves incident on it. Additionally, a wedge is connected to the meta slab, which is attached to the external surface of a pipe, allowing the transmission of elastic waves that have passed through the meta slab to the pipe. The meta slab consists of an anisotropic medium, and its thickness satisfies the equation: d=m·n·λ/4, where n/2−n/2=odd. This design enables highly efficient flow velocity measurement.
