In this paper (i) shielding effectiveness of shielded enclosure with single and multiple apertures (ii) Radiation from PCB without shield (iii) Radiation from PCB with shield are analyzed using computational electromagnetic software tool-FEKO. Electromagnetic shielding involves shielding components from electric and magnetic fields and also preventing electronic devices from sending them out. In order to achieve electromagnetic compatibility, mainly with respect to radiated emission and radiated immunity it is required to have a good shielding effectiveness for the equipment enclosure. Shielding Effectiveness is defined as the ratio of the input field of the unshielded load to that of the shielded one. The shielded enclosure is modelled with both single and multiple apertures. The shielding effectiveness of both enclosures are found. The PCB is modelled with a ground plane at the bottom and a trace at the top. Then the radiations from PCB are analyzed, before and after the shield. The height of the PCB which is kept inside the enclosure is varied to find the variations in radiation.Keywords

In this paper, (i) Shielding effectiveness of shielded enclosure (ii) radiation from PCB with and without the shield are analyzed using computational electromagnetic software tool-FEKO. Electromagnetic shielding involves shielding components from electric and magnetic fields and also preventing electronic devices from sending them out. In order to achieve electromagnetic compatibility, mainly with respect to radiated emission and radiated immunity it is required to have a good shielding effectiveness for the equipment enclosure. Shielding Effectiveness is defined as the ratio of the input field of the unshielded load to that of the shielded one. The shielded enclosure is modeled with a single aperture in x-z plane and shielding effectiveness of this enclosure is obtained for various incident angle. The PCB is modeled with a ground plane at the bottom and a trace at the top and radiations coming out from this PCB are obtained at various directions. Then the PCB is kept inside the shielded enclosure and the emission from PCB is obtained at various directions. In this case, the PCB acts as the load. The importance of electromagnetic shielding is revealed through this paper.Keywords

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.Keywords
