Shielding Effectiveness of anisotropic materials: How to measure?

Abstract

In a number of applications, due to concerns such as weight and flexibility, shielding materials are used with anisotropic materials. Typically, in the case of some conductive textile materials, conductive yarns are only used in one direction (warp). Other materials will have different conductivity as a function of the direction, such as deployed metal grids. In this paper, measured Shielding Effectiveness SE results obtained by using different measuring setups are compared and discussed.
