MEASUREMENT OF ELECTROMAGNETIC INTERFERENCE SHIELDING

This paper presents a review summary of radiated emission and interference shielding methodologies currently describes in brief on Electromagnetic interference measurement system allow measurement and reducing of electromagnetic interference by using electromagnetic interference shielding effectiveness. To use shielding technique as a coaxial holder with uniform diameters that maintains 50 ohm impedance throughout the length of the device. The EMI tester was calibrated and the shielding effectiveness of common and new materials was determined through several experiments.
