The frequency range is widely used in modern devices and devices

Сверхвысокий частотный диапазон - это electromagnetic radiation, which is in the spectrum between the high TV frequencies and the frequencies of the far infrared region. In English-speaking countries, it is called the microwave spectrum, because the wavelength is very small compared to the broadcast wave.

These intermediate variations are betweenlight radiation and the usual radio spectrum, so they have both the properties of light and radio waves. Just like light, they propagate in the form of a beam and are reflected. It is characteristic of such waves and the spread in a straight line, and overlap with all solid objects. Therefore, many radar antennas are enlarged optical elements in the form of mirrors or large lenses.

It is worth noting that the frequency range hassimilarity with the radiation of broadcasting and, accordingly, will be generated by the same methods. Microwave radiation consists of the classical theory of radio waves, so it is successfully used as a means of communication. However, it is very important that it has higher frequencies and due to this it is possible to get more opportunities for the transmission of information - this helps to increase the efficiency of communication. The similarity with light radiation helps to be useful for radar and other applications of technology.

This frequency range also applies insatellite communications for the transmission of a particular information over long distances. With the help of special electronic devices, the microwave signal is amplified and retransmitted, which is transmitted by ground stations. The first such bases appeared in the 60s of the last century, when they were used to broadcast TV broadcasts.

Based on past experiencespecial satellites for intercontinental communications. Currently, this ultra-high frequency range helps millions of people watch thousands of channels at a high quality level. It can also be used to transmit telephone, television, facsimile signals and digital data.

In the modern world, ultrahigh frequencyrange is the heat treatment of food at home and in food processing plants. The energy that is generated by special powerful lamps is concentrated

i'm in small volume and so it happensthermal processing of food. Thanks to these rays, the microwave and microwave ovens work silently, they are compact and clean. Such devices have been successfully used in kitchens in airplanes, in railway cars, restaurants and in vending machines on the streets, where you need to quickly cook some dishes.

Необходимо отметить, что огромную роль при The study of the electronic properties of various solids played precisely the microwave radiation. The magnetic field range helps free electrons rotate in a plane that is perpendicular to the direction of this magnetic field. In addition, if microwave radiation is directed to a solid body, then it will be strongly absorbed. This phenomenon is a cyclotron resonance, and it can be used to measure the effective mass of an electron. Using such measurements, scientists have obtained a lot of valuable information about semiconductors and their electronic properties, as well as about metals and metalloids.
