Eddy current testing (ECT) has been employed as a traditional non-destructive testing and
evaluation (NDT&E) tool for many years. It has developed from single frequency to multiple …

Sensor design and signal conditioning of eddy-current testing are essential research areas
for quantitative testing and evaluation. However, crack quantification relies on the variations …

This paper presents machine learning classification on simulated data of permeable
conducting spheres in air and seawater irradiated by low frequency electromagnetic pulses …

Lorentz Dispersion regime is a narrowband spectral region characterized by a sharp
resonance dip and an anomalous phase response. Due to its high dispersive nature, the …

A limited ability to discriminate between different materials is the fundamental problem with
all conventional eddy-current-based metal detectors. This paper presents the use …

Metal detector is widely used in food security and industrial manufacture. In order to solve
the product effect problem which used only amplitude feature, the dual channel digital …

Eddy current testing (ECT) is a non-contact inspection widely used as non-destructive
testing and evaluation (NDT&E) of pipeline and rail lines due to its high sensitivity to surface …

The paper shows application of nontraditional excitation signal Sinc for metal detection and
discrimination of detected objects. It also briefly describes characterization of Sinc signal …

In this paper we present an investigation into using the swept frequency excitation for the
inductive metal sensor. The frequency sweep excitation mode allows collecting eddy current …

Food product contamination is a hazard to human health. Therefore, we can see increasing
demand for Metal Detectors. To guarantee the safety and robustness of food product metal …
