This paper discusses correlation between results of electric and magnetic field simulation using Finite Element Method (FEM) and laboratory measurements of electromagnetic shielding effectiveness. The study shows that the addition of the MWCNT filler to HDPE base matrix tends to increase the electrical conductivity and helps in reduction of the Electromagnetic field in terms of radiated emission. With the increase in the weight percentage of MWCNT filler, improvements in terms of reduction in electromagnetic field is achieved. Addition of nano nickel to the HDPE improves the shielding efficiency. The results of this study has helped in achieving the optimum filler concentration in HDPE nano composite for improved EMI Shielding effectiveness

With the increase in the weight percentage of MWCNT filler, improvements in terms of reduction in electromagnetic field is achieved. Addition of nano nickel to the HDPE improves the shielding efficiency. The results of this study has helped in achieving the optimum filler concentration in HDPE nano composite for improved EMI Shielding effectiveness
