A research team in Korea has experimentally demonstrated, for the first time in the world, a nonlinear wave phenomenon that changes its frequency—either rising or falling—depending on which direction ...

Engineers are familiar with using the Fourier transform to convert between time-varying signals and their corresponding frequency spectrum. What is not as familiar is that spatially varying signals, ...

Components of a typical laser include gain medium, laser pumping energy and resonant optical cavity. The output frequency of most lasers is fixed or within a small range, and it is difficult to ...

Dispersion-designed structural geometry enables group-velocity mismatch of interacting lights to be smoothed to zero, for wide-range frequency conversion. Advancements in quantum information ...

This is the sixth in a series on the LLC converter. The LLC converter is very complicated which explains why Reference 1 is a PhD dissertation on this circuit. I attended Virginia Tech and I can tell ...
