Study of Techniques for Measuring the Electromagnetic Shielding Effectiveness of Materials

摘要

The report covers a number of measurement approaches which are studied, including the use of a shielded room, coaxial transmission line holders, time domain signals, the dual TEM cell, and an apertured TEM cell in a reverberation chamber. In each case the system's frequency range, test sample requirements, test field type, dynamic range, time required, analytical background, and present data taken on a common set of materials are considered.
