Using nested reverberation chambers to determine the shielding effectiveness of a material



Jason B. Coder, John M. Ladbury, Christopher L. Holloway


We examine the current method for determining the shielding effectiveness of a material using nested reverberation chambers and show a simplified approach. Included in our examination is a discussion of the purpose for using a four antenna measurement system and a simplification of the equations used in the data processing portion of the measurement. The result of this simplified approach will be a measurement process that is more intuitive and makes use of S parameters along with power ratios in all portions of the measurement effort. To validate our simplifications and data processing methods, we will provide an experimental demonstration and verification.
