EMP or Electro Magnetic Pulse is called sometimes as transient electromagnetic disturbance. This is more of a short burst of electromagnetic energy which should not be taken lightly. 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 like a lightning strike is enough to destroy physical objects like aircraft structures, buildings and so on. The management effect for EMP is vitally important branch of EMC or Electromagnetic compatibility engineering. The truth is, EMPs today are weaponized in order to deliver the damaging effect it has to enemies.
To safeguard our devices from unexpected events, Faraday cage can be used. 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 works by layering non conductive and conductive layers, creating a shielding effect for items that are stored inside the cage and protecting 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 – first thing you have to do is wrap your device inside the plastic wrap or put it in plastic bag. This will create barrier between conductive aluminum layer and the device. Aside from protecting your device from EMP, this can protect it as well from water.
Step number 2. Cover every inch of your device with aluminum foil – the reason to why this must be done is that, aluminum foil serve as conducting layer. In order for this one to be effective, make sure that the aluminum foil you’re using has no gaps or tears. In molding the foil around the device, it is great if you’d use your hands. This act as the first 3 layers of aluminum foil.
Step number 3. Alternate the aluminum foil and plastic – you need to cover every inch of the device with three layers of aluminum foil. You can also maximize the protection by simply adding plastic layers in between every layer of the foil. 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.
