A research team has demonstrated that silicon nanospheres can strongly enhance second-harmonic generation (SHG) from an ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

Fast radio bursts (FRBs) are a kind of energetic cosmic radio burst. Though their duration is usually at millisecond scale, their energy (estimated isotropically) reaches 10 ^36 ～10 ^41 erg, ...

The technique in this article explores applied radio frequency fields B 1 expressed and employed as nutation frequencies for nucleus i,ƒ (1,i) =1/2π |1/2 γ i B r,i |, vital constraints in solid-state ...
