Introduction

Junjun Xin, an accomplished inventor based in Ronkonkoma, NY, has made significant contributions to the field of electromagnetic acoustic transducer (EMAT) technology. With two patents to his name, Xin's work focuses on advancing the efficiency and effectiveness of EMAT systems in various applications.

Latest Patents

Junjun Xin's latest patents include innovative designs that enhance the functionality of EMAT sensors. The first patent is for a **Power supply for electromagnetic acoustic transducer (EMAT) sensors**. This system incorporates a power supply designed to provide output power to the EMAT sensor. It features a DC/DC converter to boost input DC voltage to a higher DC voltage, a DC/AC inverter with Silicon Carbide (SiC) Mosfet power switches to convert the boosted DC voltage into an AC square voltage, and an output filter that transforms the AC square voltage into a smooth AC sinusoidal voltage, which serves as the output power for the EMAT sensor.

The second patent is for an **Electromagnetic acoustic transducer (EMAT) for both lamb and shear horizontal wave transduction**. This device is capable of generating both Lamb waves and shear horizontal (SH) waves, or Lamb waves exclusively. The EMAT is configured with first and second coils that are shifted in alignment relative to one another, along with a magnet array positioned above the coils. By exciting the first coil with electrical current, the EMAT generates a Lamb wave; conversely, by activating the second coil, it produces a SH wave. Additionally, the EMAT can feature a movable coil and magnet array, allowing for wave generation by adjusting their positions.
