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…
