Latest Patents

Ali is credited with 1 patent, titled “Defect Sizing Combining Fixed Wavelength and Variable Wavelength Guided Waves.” The invention describes a system and method for estimating the size and geometry of defects in solid structures.

The system uses a magnetostrictive-strip electromagnetic acoustic transducer (EMAT) with a static biasing magnetic field, RF coils for fixed- and variable-wavelength measurements, and a strip of highly magnetostrictive material coupled to the structure. Fixed-wavelength measurements assess the amplitude and frequency content of signals reflected or attenuated as they travel through the structure. Variable-wavelength measurements record which frequencies are cut off or pass through it. The fixed-wavelength assessment helps determine whether the variable-wavelength estimate is valid, and the final defect assessment may rely on either estimate or combine both.

Career Highlights

Ali’s patent focuses on combining complementary guided-wave measurement techniques to evaluate structural defects. The approach is designed to support estimates of defect size and geometry.

Collaborations

Ali’s listed coworkers include Borja Lopez Jauregui and Dileep Koodalil.

Conclusion

Syed Ali’s patented guided-wave system combines fixed- and variable-wavelength measurements to help assess defects in solid structures.
