dc.description.abstract Assembling of a large number of high frequency electronic devices in a congested area has gradually been increased. This creates electromagnetic interference (EMI) which causes malfunctioned or abnormal operation devices: For this reason 'mote and more 'effective EMI shielding is required among the devices. Moreover, to minimize the health hazards from the electromagnetic radiation from high frequency devices like cell phones., proper effective shielding should be used for those devices. Nowadays metal is the mostly used EMI shielding material. Metal based shielding materials have heavy weight. They also suffer from mechanical 'corrosion and 'erosion. Due to tower thermal -conductivity ,they cannot be used in a hot environment, where rapid heat dissipation is necessary. The aim of this thesis is to compare the EMIshielding efficiency of Metal with that of Single Walled Carbon Nanotubes (SWCNT). For that purpose we derived the analytical expressions for the shielding efficiency of any materials. From the results obtained in this work, it is found that SWCNT offers better EM! -shielding efficiency than that 'Of metal {copper and stainless -steel). -Compared with metal, SWCNT offers much less weight, higher thermal conductivity and mechanically hard. Therefore" SWCNT can be the best option as an EMI shielding materials instead of Meta. en_US
