Abstract:

Nickel coated polycarbonate film has been investigated to determine its shielding effectiveness (SE). A method to measure the SE is to place the coated film in an open side of a metal square box (3"x3"x3") and then expose to RF Source. Using the U.S. Military Standard 285 [1] and revised version of ASTM-D4935 [2] as reference and at 100 Mhz to 3 Ghz frequency range, the SE of nickel coated on polycarbonate film can be experimentally determined by taking the difference between the RF Signal with and without the shield as measured using Advantest R3131A Spectrum Analyzer.
