In the last few weeks I've been working on a slightly more formal version of this post on black-body radiation for use in something else. One of the tricky things in writing about the development of ...

The spectral manipulation of photons is essential for linking components in a quantum network. Large frequency shifts are needed for conversion between optical and telecommunication frequencies, while ...

Spectroscopy, in its broadest sense, is the term given to the investigation and measurement of spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter ...

Adjust the colors to reduce glare and give your eyes a break. Use one of the services below to sign in to PBS: You've just tried to add this video to My List. But first, we need you to sign in to PBS ...

Spectrum is everything when it comes to choosing or designing wireless equipment. Knowledge of the electromagnetic (EM) spectrum is essential for all engineers working with wireless equipment and ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

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 ...
