Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

The effects of Fresnel Zone in communication theory based on radio waves

Bulletin de la Société Royale des Sciences de Liège, 2016
As the visible light absorption of radio waves also have the ability to be absorbed. Radio waves are also based on the principle of focusing obey the laws of physics. Or the phase shift of focus in telecommunications is an important factor for Radio Communications, which includes discussion is lengthy.
