The Function of EMP Bags
Transient electromagnetic disturbance is more popularly known as EMP or Electro Magnetic Pulse. This is basically a short burst of electromagnetic energy but it is something that shouldn’t be underestimated. The pulse has originated from natural occurrence and also, this can be manmade and might occur as an electric, radiated, conducted electric current or magnetic field all of which will depend on source.
The interference created by EMP is oftentimes disruptive or damaging to the electronic devices and equipment. And given with higher energy level, a strongly powerful EMP such as lightning strike is capable of destroying objects including 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.
This is the time when Faraday cage was invented. In reality, this is named after Michael Faraday and it is a form of device that is designed to protect electronic devices from any type 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.
And if you would like to know how this can be carried out, then be sure that you are going to follow the steps in the next paragraphs.
Step number 1. Wrap your electronic device in plastic layer – wrap the device inside a plastic wrap or put it in the plastic bag. This is going to create barrier between the 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. Ideally, use your hands to mold the foil around your device. This is basically the first of 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. In between layer, it is recommended to add plastic layer to be able to maximize the protection it makes. By doing so, it will be able to create alternating layer of both conductive and non-conductive materials and thus, protect your device from electromagnetic radiation.
