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.
Electromagnetic waves are predominantly present in the air, especially in areas with communication masts. When in the air, they often interfere with the correct operation of certain types of equipment. This disturbance is what is often referred to as electromagnetic interference.
Some companies have a specialty in manufacturing shields that help lock out disruptive waves from equipment. Many technological products rely on this type of protection to function correctly. Among the areas that manufacturers like to keep an eye on is the transmission equipment for electronic media. These days, television cables come with shields that help prevent the possibility of interference through radiation.
Without protective measures, you would have a hard time viewing clear pictures on your TV. The medical sector is also heavily reliant on the technology. Medical machines always ought to stay shielded if mechanical failure that may cause deaths is to be avoided.
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.
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.
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.
