Evaluation of radiating-source parameters by measurements in Faraday cages and sparse processing

We have developed an algorithm that enables characterization of radiating sources by amplitude measurements in a Faraday cage. The algorithm uses equivalent dipoles and exploits electromagnetic scattering from the cage walls. To extract the parameters of the equivalent dipoles, we use sparse processing. We have verified the proposed approach by comparing experimental results obtained in an anechoic chamber and in a Faraday cage. In this way, we have shown that the Faraday-cage measurements may be used as a low-cost alternative to the standard electromagnetic-compatibility test sites such as (semi)anechoic chambers and open-area test sites.
