With the rapid development of the times, radio frequency microwave has become a multidisciplinary field with high potential and high development trend in people's daily life. Today we will take stock of the basic characteristics, advantages and applications of RF microwave.
Basic characteristics of RF microwave:
1. Photolike
RF microwaves can propagate at the speed of light in a straight line in air or other media like light, and there are incident and reflection phenomena on different media interfaces, because the wavelength of RF microwaves is very short, which is much smaller than the geometric size of general objects. At the same time, when RF microwaves are irradiated on these objects, there will be obvious reflections, and some objects will have specular reflections.
2. Penetration
When RF microwaves irradiate certain objects, they can penetrate deep into the object, and microwave (especially centimeter-band) signals can penetrate the ionosphere and become a cosmic serial port for people to detect outer space; they can penetrate clouds, vegetation and the surface layer, and have The ability to work around the clock is an important means of remote sensing technology. It can also penetrate biological tissues and is an important method of medical diathermy. It can also penetrate plasma and is an important means of plasma diagnosis research.
3. Non-ionizing
In general, the quantum energy of RF microwaves is not large enough to change the internal structure of material molecules or destroy the bond structure of material molecules. From the subject of physics, under the action of the periodic force of the external electromagnetic field, the molecules, atoms and nuclei in the substance will produce a variety of resonance phenomena, many of which are in the RF and microwave frequency range, which provides a powerful experiment for the study of the internal structure of the substance means, thus forming an independent sub-discipline—microwave spectroscopy. On the other hand, the RF and microwave resonance characteristics of materials can also be used to develop RF microwave components with certain specific materials to complete the establishment of the system.
4. Informative
The RF microwave frequency band is thousands of times wider than the ordinary medium wave short wave and ultrashort wave, which means that the RF microwave can carry far more information than ordinary radio waves, so modern mobile communication, multi-channel communication, image transmission, satellite communication And other equipment all use video microwave as the means of transmission.
RF and microwave can also provide phase information, polarization information, Doppler frequency shift information, etc., and are widely used in target detection, target feature analysis, telemetry and remote control, remote sensing and other fields.
Compared with ordinary radio waves, RF microwaves have the following characteristics:
1. Wide frequency band, large amount of information that can be carried
2. High resolution, clearer imaging and sensitive response
3. Small size
4. Less interference
5. Fast
6. The spectrum is not crowded and not easy to be blocked
