“…SE in conducting polymer-based composites depends mainly on absorption, and so these composites may also find application in the field which require absorption of EM radiation such as stealth technology. Mkel et al used polyaniline as a shielding material and for making Salisbury structure in the frequency range of 100 kHz to 110 GHz and 0.1 to 1000 MHz [18,19]. Phang et al have reported the EMI shielding behaviour of PANI/TiO 2 composite and in another work used Fe 3 O 4 and TiO 2 [20,21].…”

This communication reviews current developments in carbon nanostructure-based composite materials for electromagnetic interference (EMI) shielding. With more and more electronic gadgets being used at different frequencies, there is a need for shielding them from one another to avoid interference. Conventionally, metal-based shielding materials have been used. But due to the requirement of light weight, corrosion resistive materials, lot of work is being done on composite materials. In this research the forerunner is the nanocarbon-based composite material whose different forms add different characteristics to the composite. The article focusses on composites based on graphene, graphene oxide, carbon nanotubes, and several other novel forms of carbon.

We report a theoretical research for the condition of electromagnetic shield breaching when a narrow aperture is punctured in thin metal film. To calculate electromagnetic field transmission through a narrow slit, a Rayleigh wave expansion has been applied for free standing, thin metal film. We found that the DC electric field allows perfect transmission when the length of the slit is infinite, regardless of the other geometrical factors such as slitwidth and thickness. Slitwidth dependent transmission spectra as a function of frequency shows a cutoff frequency that decreases almost linearly to the slitwidth, giving that almost successful shielding is only possible when the slitwidth is smaller than 1 micron.

“…PANI has attracted much attention because of its potential application in molecular electronics, electromagnetic interference (EMI) shielding, chemical sensors, antistatic coatings, rechargeable batteries, corrosion inhibitors, absorbing materials [3][4][5][6][7], etc. It is well known that conducting polymers can effectively shield electromagnetic waves generated by an electric source.…”
