Electromagnetic Interference, Shielding effect, Reflectivity, Absorption


Electro-magnetic interference is one of the biggest problems which hinder electrical and/or electronic devices from operating efficiently in addition to the negative impact it can have on environment. However, with proper shielding, unwanted electromagnetic interference can be substantially reduced, hence to achieve better EM compatibility among devices and avail safer environment. This paper presents multi-layered electromagnetic shield design analysis by considering different scenarios. The analysis is based on simulation done using MATLAB
