If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to ...
A medium’s refractive index (n) describes how the oscillating electric field of a light wave causes the disturbance of electrons which subsequently emit light. This emitted light will be out of phase ...
Mid-infrared (MIR) spectroscopy is a powerful tool for characterising the vibrations of molecular bonds and is therefore ideal for label-free detection of chemical species. Recent research into ...
