Four-wave mixing (FWM) is a nonlinear optical phenomenon occurring in fibre-based Wavelength Division Multiplexing (WDM) systems, where the interaction among multiple channels produces additional ...

New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and ...

One of the deepest mysteries in quantum physics is the wave-particle duality: every quantum object has properties of both a wave and a particle. Nowhere is this effect more beautifully demonstrated ...
