Prediction of Shielding Effectiveness of Cables used for Automobile Sector: Technical Note

The automotive industry is gearing for a drastic shift towards the electric vehicles and also leaping for the autonomous vehicles. The functional performance of such autonomous vehicles must be properly ensured. One such kind of disturbance to the proper functioning of the vehicle is Electromagnetic Interference due to presence of various electrical systems. The operating frequency range is increasing due to latest advancement in automobile industry. The future working frequency is going to be 74GHz which falls under extremely high frequency range. So it is inevitable to analyse the electromagnetic interference and emission caused by such futuristic models. The electromagnetic field effect is dependent on the shielding effectiveness. The Electromagnetic Shielding Effectiveness (EMSE) varies with numerous parameters like the type of material, shape of material, size of material etc. The work deals with the modelling of cable and study on shielding effectiveness of the cables used in automotive. The same has to be evaluated with standards test procedures and validated.
