The physical characteristics of a plasma arc affect the stability of the keyhole and weld pool directly during keyhole plasma arc welding (KPAW).There will be s
We study the fractal rhythm in the ionization of Rydberg helium and lithium atoms in an electric field by using the semiclassical method.The fractal structures
A promising tool to detect micro-cracks in plate-like structures is used for generating higher harmonic Lamb waves. Inthis paper, a method combining nonlinear S
Antenna-coupled field-effect-transistors (FETs) offer high sensitivity for terahertz detection.Both the magnitude and the polarity of the response signal are se
