About
P. R. Underhill is a researcher specializing in non-destructive evaluation (NDE) and electromagnetic testing methods, with a particular focus on the inspection of aerospace structures. Their work centers on advancing eddy current testing (ECT) techniques to improve the reliability and precision of structural assessments in aviation applications. Underhill's most notable contribution involves the development of multi-frequency eddy current testing for aluminum honeycomb sandwich aircraft panels — a class of lightweight structural components widely used in modern aircraft. Traditional inspection of surface damage on these panels relies on manual measurement, introducing variability dependent on inspector skill and judgment. Underhill's research demonstrated that ECT's inherent sensitivity to probe-to-specimen spacing, known as lift-off, can be strategically leveraged to enable high-resolution surface profiling and core evaluation, effectively automating and standardizing what was previously a subjective process. This work, published in 2017, has accumulated citations across multiple venues, reflecting its relevance to both the research community and the aerospace inspection industry. By bridging the gap between fundamental electromagnetic sensing principles and practical aircraft maintenance challenges, Underhill's contributions support safer, more consistent, and more efficient inspection protocols for critical aerospace structures.
