Electricity is an important topic in education. However, basic education does not adequately cover the all important concept of EMI shielding. With many applications in industry, its theoretical bit is only fully covered in science oriented courses offered in higher learning.
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.
Certain companies are known to manufacture protective equipment for the purpose of countering the effects of this sort of interference. Electronics usually ought to be shielded in order to function as required. Electronic transmission is a major area that manufacturers like to focus on. Nowadays, TV cables have shields that actively safeguard the information they transmit from disruptive radiation.
Without a shield, your TV set would not display clear pictures all the time. Its application goes as far as in the medical sector. Modern electronic machines used in hospitals ought to function without any disruption as it could be the difference between life and death.
Circuits are commonly shielded through the use of metal. Protective edges may be created using metal screens, metal foam or sheet metal. When put into practice, protective meshes ought to have smaller holes than the wavelengths of interfering elements. If the holes are larger, smaller disruptive waves may pass through and cause electronic equipment to malfunction or not function at all.
Nowadays, electronic appliances typically come enclosed in plastic. Despite the fact that plastic is permeable to radiation, plastic encased appliances have metallic coatings in their interiors. Most coatings are made using copper and nickel. For evenness and proper conduction, the metals are usually ground into small bits then sprayed on the encasing.
Another great application of the concept can be found in microwaves. Their doors have protective screens built around the window. Microwaves typically have wavelengths of 12 centimeters. By applying Faradays law, the protective screen and metal encasing in a microwave confines the dangerous rays within its enclosure and at the same time keeps interference out.
When transmitting radio waves, protective technology ensures there is no loss of sensitive data from chips. Most biometric passports use chips to store data. With identity theft a major issue, protection is a major concern for authorities.
Data loss is a major issue in computing as well. Hackers always target unsecured computers in a bid to get sensitive information. However, a keyboard shield can prevent an intruder from accessing information passively as it is keyed using a keyboard. The prohibitive costs that are synonymous with this application confine it to the military nonetheless.
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.
