Latest Patents
One of Lei Zhu's latest patents is the "Reconfigurable wideband phase-switched screen based on artificial magnetic conductor." This invention discloses a reconfigurable wideband phase-switched screen (PSS) that utilizes an artificial magnetic conductor (AMC). The design allows for the control of gap capacitance between patches by adjusting the capacitance of varactors. This results in periodic units that can achieve multiple continuous frequency points. The phase difference between two adjacent frequency bands ranges from 143° to 217°, enabling the structure to absorb incident electromagnetic waves across a wide frequency band. The broadband PSS boasts a relative bandwidth of 45.2%. The AMC structure is noted for its simplicity and ease of processing, with a thickness less than one twentieth of the working wavelength, significantly reducing size and costs.
Another significant patent is the "Independent suspension system and crane having same." This independent suspension system features two suspension oil cylinders positioned between the wheels and the frame. It includes a steering mechanism driven by a steering booster oil cylinder, allowing the wheels to turn. The system also incorporates two swing links corresponding to the wheels, with each link hinged to a wheel hub via a spherical hinge. This innovative design enhances the functionality of cranes equipped with the independent suspension system.
