Calibration and analysis of coaxial holder for measuring shielding effectiveness of materials

Abstract

The circular coaxial holder test method is a simple way to measure the far-field shielding effectiveness of plate composite material. It‘s dynamic range and theoretical base is good, but there are some problems should be solved careful1y:The calibration method, accuracy and repeatability owing to unstable contact resistance, impedance mismatch and s o on.This paper deals with these problems. The test results given for calibration sample is consistent with the theoretical analysis.
