Microwave photonics studies electromagnetic waves at wavelengths between one millimetre and one meter. Such waves are important for communications systems as well as remote sensing; their detection is crucial in a variety of applications including astronomy. Microwave photonics takes advantages of strengths of photonics systems- e.g. fibre links – and applies them to microwave radiation. Due to the frequencies involved, this area is a key region of overlap between photonics and high-frequency electronics systems, and for this reason it has been the focus of research in the physics and engineering communities in the past few decades.
This Collection brings together original research in the topic of microwave photonics, including development in the generation, transports, processing, and detection of microwave signals.
