Electromagnetic Acoustic Detection of Steel Plate Defects Based on High-Energy Pulse Excitation
The conventional electromagnetic ultrasonic transducers (EMATs) rely on the static magnetic field created by magnets. The magnet increases the size of the EMATs, and the strong magnetic force of the magnet attracts the detected steel and even ...

Theory of directed transportation of electronic excitation between single molecules through photonic coupling [PDF]
The primary result of UV-Visible photon absorption by complex organic molecules is the population of short-lived electronic excited states. Transportation of their excitation energy between single molecules, formally mediated by near-field interactions ...
