Capacitive imaging using fused amplitude and phase information for improved defect detection
Silvio Amato, David Hutchins, Xiaokang Yin +2
This paper introduces an improved image processing method usable in capacitive imaging applications. Standard capacitive imaging tends to prefer amplitude-based images over the use…
Quantitative Evaluation of Crack Depths on Thin Aluminum Plate using Eddy Current Pulse-Compression Thermography
Qiuji Yi, Hamed Malekmohammadi, Gui Yun Tian +2
Eddy current stimulated thermography is an emerging technique for non-destructive testing and evaluation of conductive materials. However, quantitative estimation of the depth of s…
A low-cost flexible instrument made of off-the-shelf components for pulsed eddy current testing: overview and application to pseudo-noise excitation
Hamed Malekmohammadi, Andrea Migali, Stefano Laureti +1
A flexible and low-cost device for eddy current non-destructive testing made of off-the-shelf components is described. The proposed system is compact and easy to operate, and it co…
Trapped air metamaterials for ultrasonic sub-wavelength imaging in water
Stefano Laureti, David A. Hutchins, Lorenzo Astolfi +8
Acoustic metamaterials constructed from conventional base materials can exhibit exotic phenomena such as negative refractive index, extraordinary transmission-absorption and sub-wa…
Skyrmion based microwave detectors and harvesting
G. Finocchio, M. Ricci, R. Tomasello +6
Magnetic skyrmions are topologically protected states that are very promising for the design of the next generation of ultralow-power electronic devices. In this letter, we propose…
Micromagnetic study of electrical-field-assisted magnetization switching in MTJ devices
M. Carpentieri, R. Tomasello, M. Ricci +2
Perpendicular MgO-based Magnetic Tunnel Junctions are optimal candidates as building block of Spin Transfer Torque (STT) magnetoresistive memories. However, up to now, the only STT…
Chirp spectroscopy applied to the characterization of Ferromagnetic Resonance in Magnetic Tunnel Junctions
M. Ricci, P. Burrascano, M. Carpentieri +2
Magnetic Tunnel Junction devices find use in several applications based on the exploitation of the Spin-Transfer Torque phenomenon. The Ferromagnetic Resonance curve is a key chara…
From Chirps to Random-FM Excitations in Pulse Compression Ultrasound Systems
Sergio Callegari, Marco Ricci, Salvatore Caporale +6
Pulse compression is often practiced in ultrasound Non Destructive Testing (NDT) systems using chirps. However, chirps are inadequate for setups where multiple probes need to opera…
