MICROWAVE ABSORBING STRUCTURE WITH CONDUCTING POLYMER FSS COATING

Harmful electromagnetic(EM) waves from various sources, such as mobile phone, portable music player, hair dryer, wireless devices are considered as the serious environmental pollution of the day. The superfluous electromagnetic waves are widely known as the cause of EMI(electromagnetic interference) problems in electrical devices as well as the source of disease in human body. Recently, many kinds of precautions and legislations are developed to verify and prevent the harms from EM waves on the human body but just avoidance and shielding with conductive materials cannot be the basic solution. Only the development of extensive EM wave absorbing medium could be the essential measures on the problems. The “conducting polymers” have the possibility to be the solution. In this study, EM wave absorbing material and structure based on the intrinsic conducting polymer was suggested and the absorbing characteristics were verified to make the EM protective composites.
