This article is the first part of a trilogy that aims to introduce a new paradigm in the measurement of specific electromagnetic shielding materials, namely shielding materials made from woven conductive threads. These articles highlight the shortcomings of common methods in the evaluation of such materials and introduce new approach and methodology to measure them. This new paradigm emphasizes characterization of shielding materials based on magnetic field rather than electric field. The new method introduces a measurement setup and lumped element model intrinsic to the material and independent from the measurement method.
