Electronics, Photonics and Cyberphysical Systems

The merging of microwave and photonic sensing is a logical and powerful trend that creates an ideal synergy: microwaves provide penetration through materials and media, photonics provide the highest spatial resolution and accuracy. This is a transition to fault-tolerant systems, where the physical limitations of one technology are completely offset by the strengths of another. In fact, this is the path to creating “all-seeing” sensors. The main challenge of such a merger is the synchronization of heterogeneous data and their processing in real time, which requires a developed search and analysis tool. However, the creation of new hardware cannot be downplayed in its influence on the development of “all-seeing” sensors, since developments are moving in opposite directions and the resolution of signal processing in radio-photonic systems significantly exceeds the resolution of photonic ones. Some scientists skeptically compare this resolution to the size of a hydrogen atom.In fact, this is real in the most common wavelength range of information and telecommunication systems, which lies in the region of 1552.52 nm. Based on this, let's move on to the contents of the issue, the main topic of which was microwave and photon sensors and the issues of constructing combined systems based on them.
