Traditional visual inspection methods fall short in detecting delaminations, which has driven the development of advanced non-destructive testing methods, including ECT.

In this context, defects are mathematically modeled as additive changes in the material's electrical conductivity tensor, allowing for detailed analysis of their impact on electromagnetic properties.

Experimental results have shown that the best estimates for delamination sizes are achieved using specific threshold values, indicating a refined approach to defect characterization.

In tests utilizing the NEU-DET and GC10-DET datasets, the proposed model demonstrated remarkable detection accuracies of 99.3% and 99.2%, respectively, showcasing its effectiveness.

CFRPs are increasingly favored in aerospace and automotive sectors due to their high strength-to-weight ratio and fatigue resistance, making their integrity critical.

The integration of numerical simulations, especially the Finite Element Method (FEM), has enhanced the modeling of electromagnetic interactions, optimizing probe configurations for better accuracy.

Despite these advancements, challenges persist in calibrating ECT systems and ensuring sensitivity to environmental conditions, which can affect testing effectiveness.

A recent review highlighted the latest advancements in eddy current probe design and its applications across various industries, including aerospace and automotive, emphasizing its growing importance.

Eddy current testing (ECT) is a crucial non-destructive testing technique that identifies surface and subsurface defects in conductive materials, leveraging electromagnetic induction for defect detection without physical contact.

Recent studies have focused on enhancing ECT capabilities, particularly through the use of high-frequency probes and innovative coil configurations, which have significantly improved defect detection in carbon fiber-reinforced polymers (CFRPs).

Delaminations in CFRPs are particularly critical as they can lead to catastrophic failures, underscoring the need for effective detection and characterization techniques.

Overall, the study underscores the importance of innovative ECT techniques and their potential to enhance the reliability and safety of materials used in critical applications.
