EMP or Electro Magnetic Pulse is also referred to as transient electromagnetic disturbance. Basically, this is a short burst of electromagnetic energy but you should not underestimate its capacity. The pulse may have been originated from natural occurrence or it can be manmade as well and might occur as electric, radiated, conducted electric current or magnetic field depending on the source.
In most cases, EMP is creating disruptive or damaging interference to our electronic devices and equipment. At higher energy levels, powerful EMPs similar to lightning strike is more than enough to lay destruction to physical objects like aircraft structures, buildings and so on. The management effect for EMP is vitally important branch of EMC or Electromagnetic compatibility engineering. In reality, EMPs are also used by the military nowadays by weaponizing its effect.
This is when the Faraday cage was created. It was actually named after Michael Faraday and it’s a type of device that’s intended to provide protection on electronic devices from any sort of electromagnetic radiation. The cage functions by laying the non conductive and conductive layers that creates a shielding effect for items that are stored in the cage and also, to protect it from radiation. To an average individual, this seems complicated by in reality, anyone can have a DIY Faraday cage with aluminum foil.
If you wish to learn how this can be done, then make sure that you follow the steps that are listed below:
Step number 1. Wrap your electronic device in plastic layer – wrap the device inside a plastic wrap or put it in the plastic bag. What this will do is establish a barrier between conductive aluminum layer and the device. It can also serve as waterproof layer and have that additional layer of protection.
Step number 2. Cover every inch of your device with aluminum foil – the reason why this should be done is that, the aluminum foil act as a conducting layer. For this to be effective, there has to be no gaps or tears in the aluminum foil you are using. Ideally, use your hands to mold the foil around your device. This act as the first 3 layers of aluminum foil.
Step number 3. Alternate the aluminum foil and plastic – you must cover every inch of your device with at least three layers of the aluminum foil. Maximize the protection it brings by adding plastics in between layers. By doing so, it is going to create an alternating layer of both conductive and non-conductive materials and protect your device from electromagnetic radiation.
