The frequency range is widely used in modern devices and devices

Ultra-high frequency range is electromagnetic radiation, which is in the spectrum between high TV frequencies and far infrared frequencies. In English-speaking countries it is called the microwave spectrum, because the wavelength is very small in comparison with the wave of broadcasting. These intermediate oscillations are between the light radiation and the ordinary radio spectrum, therefore they possess simultaneously the properties of light and radio waves. As well as light radiation, they propagate in the form of a ray and are reflected. Characteristic of such waves is propagation along a straight line, and overlapping by all solid objects. Therefore, many antennas with radar are enlarged optical elements in the form of mirrors or large lenses.

It should be noted that the frequency range is similar to the emission of the broadcasting sphere and, accordingly, will be generated by the same methods. Microwave radiation consists of the classical theory of radio waves, therefore 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 obtain more opportunities for information transfer - this helps to improve communication efficiency. The similarity with light radiation helps to be useful for radar and other applications of technology.

This frequency range is also used in satellite communication to transmit this or that information over long distances. With the help of special electronic devices, the microwave signal, which is transmitted by ground stations, is amplified and retransmitted. The first such bases appeared in the 60s of the last century, when they were used to broadcast TV broadcasting.

Based on the experience of previous years, special satellites were developed for the intercontinental communication. Currently, such an ultra-high frequency range helps millions of people watch thousands of channels at a high-quality level. It can also transmit telephone, television, facsimile signals and digital data.

In the modern world, the ultra-high frequency range is the heat treatment of food products at home and in food processing plants. Energy, which is generated by special high-power lamps, concentrates I'm in a small volume, and so there is a heat treatment of food. Thanks to such beams, microwave and microwave ovens operate noiselessly, they are compact and clean. Such devices are 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.

It should be noted that the microwave radiation played a huge role in the study of the electronic properties of various solids . The range of the magnetic field helps the free electrons to rotate in a plane that is perpendicular to the direction of this magnetic field. In addition, if a solid body is directed to microwave radiation, then it will be strongly absorbed. This phenomenon is a cyclotron resonance, and with its help it is possible to measure the effective mass of an electron. With the help of such measurements, scientists received much valuable information about semiconductors and their electronic properties, as well as metals and metalloids.
