Abstract :

This work is about electromagnetic interference shielding, its frequency range is 1-18 GHz. The wavelength is called centimeter wave, and we do not count the wave pass. So I tried to measure the shielding ability by putting a filler in the foam to try to cover a wider range of shielding while reducing the filler.The filler is some carbon materials that are decorated with increasing electrical conductivity. When the carbon materials are modified with acid and ultra sonicating powerfully, however, the carbon properties are decreasing generally, so I used amphiphiles to decorate metals. The electromagnetic waves are reflected and absorbed out of the pores. Transmission Electron Microscope (TEM) and Micro-CT show fillers network. The filler is well contact each others and enclose foam�s pore in foam matrix. For Ag decorated on carbon materials, use SEM and Raman Spectrometer. Electromagnetic Interference shielding performance is tested with Vector Network Analysis as the 2mm thickness in 1-18GHz. Recent Publications: 1. Sanjay R. Dhakate, Kiran M.
