Scientists from Saratov University have come up with a way to improve communication in phones, radios, and Wi-Fi. They have made a real breakthrough, being the first in the world to establish the formation of Bragg resonances in plates of periodic ferromagnetic semiconductors. This was reported by the press service of the Ministry of Education and Science of the Russian Federation.
The team of scientists from SSU was the first in the world to study the formation of Bragg resonances in a plate of ferromagnetic semiconductor with a system of grooves on the surface.
The uniqueness of this approach lies in combining the properties of a magnetic material and electronic plasma. Previously, similar studies were conducted only on materials with a constant thickness, which did not allow effective control of their characteristics.
Ferromagnetic semiconductors are amazing materials that combine magnetic and electrical properties. They can become magnetized on their own and conduct electricity without the help of external forces. These materials make devices more compact and energy-efficient. When waves are reflected from periodic structures inside such materials, special effects called Bragg resonances occur.
The results of the study open up many opportunities for application. One of the main directions is the creation of energy-efficient devices for information processing.
Previously, scientists developed an effective method for compressing information about the state of the wireless communication channel, which is transmitted over Wi-Fi networks from connected devices to the access point. The new algorithm allows reducing the amount of data by 50%, which significantly improves the speed and quality of modern Wi-Fi networks.
