Electricity is certainly a crucial topic in education. EMI shielding, an important education concept, only gets covered minutely in many syllabuses. With a myriad of practical applications centered on it, the only time it gets fully covered during the course of study is when one enrolls as an undergraduate for a science based course.
Areas that have large numbers of communication masts are always bound to have electromagnetic waves. When in the air, the waves may interfere with a wide range of electronic equipment. The disturbance occasioned by the waves is commonly known as electromagnetic interference.
To counter the effects of the radiation, some companies specialize in the manufacture of shields that keep the disruptive waves at bay. Many facets of modern technology hugely benefit from this. One important area that manufacturers focus on is the transmission of electronic media. Modern television cabling systems are designed to withstand the effects of this form of radiation.
Without protection, you would not be able to view clear pictures on your TV set. The application of the technology can also be felt in the medical industry. The machines used in hospitals ought to be shielded so as to prevent deaths due to mechanical failure.
Metal is the primary material used when making shields. A protective edge may be made using sheet metal, metal foam or a metal screen. Technically, a protective mesh should have holes that are smaller in size than the wavelength of an interfering wave. Large holes may permit the passage of smaller disruptive waves, thereby causing equipment malfunction.
It is no secret that electronic goods usually come shielded in plastic. To prevent radiation from passing through, manufacturers often coat the inside of the plastic enclosures with metallic ink. The metals that are the most favored in the industry are copper and nickel. When used for this purpose, they are ground into tiny particles.
Microwaves also rely on shields to function appropriately. A microwave usually has a protective screen on its door. The wavelength of its radiation is 12 centimeters. By considering the application of the Faraday law on the flow of electromagnetic waves, the radiation that a microwave generates is confined within its metallic encasing and protective screen while outside interference is locked out.
During the transmission of radio frequency, shielding technology enables companies to prevent the theft of data stored on chips. This is a common application in biometric passports. With cases of identity theft on the rise, this is undoubtedly a great innovation.
The loss of data is also a great concern when it comes to using computers. Intruders often target weakly protected computers while on the prowl for sensitive information. However, keyboard shields are known to prevent data from being passively emitted when keyed in using keyboards. As a result of the high price of implementing the technology, it is often confined to the military.
There are many companies specializing in the manufacture of protective equipment. Most of them feature their products online. You should be able to find a solution that works for your company or household if you are a homeowner.
