How Important is EMI Shielding?
RF and EMI are caused by naturally occurring events, which means that they have always been present. Because of our modern, technological world, problems of both RF and EMI are getting worse and more noticeable. EMI and RFI are caused by the electronics we use daily. Engineers, when designing electronics, must consider EMI from the outside world and EMI created internally.
EMI Shielding
The basic concept of protecting electronics from EMI and RF dates back to the mid-1800s. Michael Faraday created the Faraday cage, more commonly referred to as EMI and RF shielding today. Michael Faraday created the device to house electronic equipment and prevent outside signals from interfering with the equipment. The cage prevents RF signals from entering the devices and stops signals from escaping into the environment.
In his initial creation, Michael Faraday did not recognize the full applications of his device. Today, there are many types of electromagnetic energy, which includes:
X-Rays: used for medical examinations, quality control, and art, these devices emit a wavelength between 10 nm to .01 nm.
Gamma-Rays: used for creating aerospace telescopes, cancer treatments, and nuclear energy, these devices emit a wavelength of fewer than 10 picometers (pm).
Microwaves: provide a viable heat source for microwave ovens. These waves are also used for radar and communicated over high-bandwidths. These devices produce wavelengths between 10 mm and 100 micrometers (μm).
