Challenges & opportunities in frequency selective surfaces for EMI shielding application: A theoretical survey

FSS provides enormous applications such as radomes, stealth technology, dichroic sub-reflector, photonic sub-reflector, military applications, antenna Technology and earth observing remote sensing instruments. Apart from this, Electromagnetic Interference shielding is the hottest research area due to advancement of mobile communication technology. The growing radiations from these mobile communication can be suppressed by transforming entire or aperture of wall in to FSS surface to protect highly sensitive equipment and human from health hazards. So this article presents the basics concepts, types and challenges of FSS especially for EMI shielding application and its theoretical investigations. Hence the various stop band filters have analyzed particularly in terms of unit cell dimension, element type and angular stability. Apart from these, tunable FSS are also discussed.
