Projeto de expansão de uma câmara de reverberação para testes de compatibilidade eletromagnética.

Abstract

The study of Electromagnetic Compatibility gains relevance each year, it is already one of the essential stages when developing an electronic project, therefore the exam of the conformity to the regulation standards and the knowledge of the measurement procedures has vital importance. These analyses and measurements are realized in specific environments, which are regulated by international standards. The Reverberation Chamber is one of these environments and its use has gained popularity in Electromagnetic Compatibility. This work aims to develop such environment, following the IEC 6100-4-21 standard considerations, for the frequency of 350 MHz. The theoretical considerations of the Reverberation Chamber as well as the particularities of its project is show. Finally, a computational model is presented and simulated through the Finite Difference Method and the gathered results are analyzed following the recommendations of the aforementioned standard.
