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 ...

Nanowire (NW) lasers with the NW simultaneously acting as gain medium and optical cavity are attractive for miniaturized photonic integration systems, which have merits of ultracompact footprint, easy ...

In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the ...

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 ...
