A SHIELDING EFFECTIVENESS of COATED CONDUCTIVE POLYMER for ELECTROMAGNETIC SHIELDING
전자파 차폐용 전도성 고분자 코팅재료의 차폐효율
Abstract
The shielding effectiveness of materials is determined by measuring the ratio of the incident electromagnetic power which passes through the material under test. To measure the shielding effectiveness materials made by conductive polymer, the flanged coaxial transmission-line holder based in ASTM D4935-89, was fabricated. This apparatus has dynamic range between 95dB and 120dB in frequency range of 50Mhz-2Ghz. Furthermore, this system can be utilized to measure the shielding effectiveness of materials produced by conductive polymer and can be adapted for shielding materials design.
