There is a wide number of problems in electromagnetic (EM) engineering that require a real-
time response or in which the input–output relationship is not a-priori known or cannot be …

Eddy current testing (ECT) is one of the non‐destructive evaluation techniques widely used,
especially in oil and gas industries. It characterized noisy data to the less‐than‐perfect …

The real-time retrieval of the characteristics of a defect with eddy current testing in a
nondestructive testing and evaluation framework is addressed. An innovative statistical …

The alternating current field measurement (ACFM) technique can be applied for surface-
breaking fatigue crack detection and sizing; the link between the ACFM signal and crack …

A microwave crack detection method using circularly polarized synthetic aperture radar
(SAR) imaging is described. The advantages of circular over linear polarization, mainly that …

Eddy current testing (ECT) has three main tasks: detection, location, and characterization of
defects. The characterization task, which means the ability to find the geometrical …

DC magnetization is generally considered to suppress the usual local magnetic permeability
variation and increase the penetration depth for magnetizing-based eddy current testing (MB …

In this study, we investigate MUltiple SIgnal Classification (MUSIC) operated at a fixed
frequency for identifying the locations of short, linear perfectly conducting cracks in limited …

This paper presents a new inversion approach to estimate the depth profile of a fatigue crack
from the output signal of an alternating current field measurements (ACFM) probe. We first …

Eddy current, especially pulsed eddy current (PEC), is known as an effective tool to detect
defects in aircraft structures. Current PEC defect classification methods require highly …
