Measurement and uncertainty evaluation for planar material's shielding effectiveness with the flange coaxial system

Shielding effectiveness of material is important research topic to meet the requirement of electromagnetic compatibility. In this paper, measurement procedure and evaluation of uncertainty of shielding effectiveness to the material on flange coaxial system are introduced. The paper describes the calculation of SE from surface resistivity and gives different comparison data. The main sources that make up the whole uncertainty are proposed.
