The global energy production model is changing from fossil fuels to renewable and nuclear
energies. Concentrated solar power is one of the growing technologies that is leading this …

The non-contact nature of electromagnetic acoustic transducers (EMATs) allows a
continuous operation at high temperatures without physical coupling. The existing high …

Circumferential shear horizontal (CSH) guided waves propagate fully parallel to the surface
of a pipe and are thus ideal for axial crack detection. At present, systems using EMATs as …

The assessment of internal thickness reduction of ferromagnetic components has always
been a critical issue in engineering. However, traditional nondestructive testing (NDT) …

Oil and gas pipeline networks require the periodic inspection of their infrastructure, which
can cause gas and oil leakage with several damages to the environment and human health …

Thermal problems occurring in glass cover, getters, vacuum, expansion bellows, and HTF
lead to significant thermal losses due to convection-conduction, which accelerates the …

This paper provided a method to improve the conversion efficiency and lessen the lift-off
effect of spiral coil electromagnetic acoustic transducer (EMAT) for some specific situations …

Terahertz metamaterial technology, as an efficient nondestructive testing method, has
shown great development potential in biological detection. This paper presents a stainless …

Removing the ambient noise and increasing the signal-to-noise ratio are very important for
detecting defects and corrosions of conductive material by using the electromagnetic …

We present an analysis of detectability of flaws in the couplings of pumping-compressor
pipes by various methods of nondestructive testing. The eddy current, magnetic particle …
