We propose a design of tunable double-band perfect absorbers based on the resonance absorption in acoustic metasurfaces with nesting helical tracks and deep-sub
We demonstrate a gain-switched Fe∶ZnSe laser pumped by a 2958nm pulsed Ho,Pr∶LLF laser.The maximum single pulse energy is 16.4μJ with a minimum pulse duratio
We demonstrate the generation of dark and bright solitons with our homemade zirconia-based erbium-doped fiber and graphene oxide (GO) saturable absorber in anom
The propagation of acoustic waves is a fundamental topic in shallow ocean acoustics.We numerically demonstrate a three-dimensional zone of silence consisting of
Apatite ceramics Ca10(PO4)6X2 (X =F,OH) were prepared by the standard solid state sintering method and irradiated with He ions under a fluence of 5 × 1016 ions
