The propagation of a probe field through a four-level Y-type atomic system is described in the presence of two additional coherent radiation fields, namely, the
Pseudospark-sourced electron beam is a promising candidate for driving vacuum electronic devices to generate mil-limeter wave and terahertz wave radiation as it
Current loss without an obvious impedance collapse in the magnetically insulated coaxial diode (MICD) is studied through experiment and particle-in-cell (PIC) s
The structural,mechanical,electronic,mechanical anisotropy,and thermal properties of boron nitride (BN) polymorphs,such as B4N4-Ⅰ and B4N4-Ⅱ,are investigated
