Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor ...

High-frequency light is useful. The higher the frequency of light, the shorter its wavelength – and the shorter the wavelength, the smaller the objects and details the light can be used to see. So ...

US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...

Distributed fiber-optic acoustic sensing is capable of continuously monitoring the spatially distributed evolution of environmental variables along a sensing fiber, thus has been extensively used in ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
