S. S. N. Srinivasa Baba and B. Giri Raju Professor of ECE, ACE Engineering College Ghatkesar, R R Dist Mrs. Srivalli Gundala Associate Professor, ECE Dept., Stanley College of Engineering for Women Abids, Hyderabad ABSTRACT Reduction of Electromagnetic Interference (EMI), i.e., shielding effectiveness of different shields against the angle of incidence with conductors and conductive polymers using plane-wave theory are carried out. The plane wave shielding effectiveness of new combination of these materials is evaluated as a function of angle of incidence for the double shield. With recent advancements in synthesizing stable highly conductive polymers, this light-weight, mechanically strong materials appear to be viable alternatives to metals for EMI shielding. The analysis is done at a particular frequency for double shield of different materials. Ke y words : Electromagnetic, Interference, shielding effectiveness and oblique incidence.

INTRODUCTION Electromagnetic Interference (EMI) is the disruption of operation of an electronic device due to either electromagnetic conduction or radiation emitted from an external source. The source may be artificial or natural, that carries rapidly changing electrical currents. The disturbance may interrupt, obstruct, degrade or limit the effective
