Abstract in Portuguese
O presente trabalho tem por objetivo avaliar o comportamento dos campos eletromagnéticos no interior de câmaras reverberantes de modos misturados através do método numérico TLM (Transmission Line Matrix). Inicialmente, apresenta-se uma descrição dos diversos tipos de câmaras aplicáveis na avaliação de desempenho de compatibilidade eletromagnética de equipamentos e sistemas elétricos, destacando-se suas principais características físicas e geométricas, com ênfase nas câmaras reverberantes. Os aspectos teóricos relacionados à descrição do método TLM são detalhados e sua aplicação na avaliação do ambiente eletromagnético das câmaras é então abordada. Diversos resultados são apresentados, considerando-se configurações pré-definidas de câmaras reverberantes, ressaltando-se a definição e cálculo de índices de mérito, bem como os principais aspectos relacionados à representação e definição de critérios adotados nas simulações destas.

Abstract in English
The aim of this report is the evaluation of the behavior of electromagnetic fields inside reverberation chambers by means of Transmission Line Modeling (TLM). Initially, it is presented a description of several kinds of chambers applicable for electromagnetic compatibility tests followed by a more detailed description regarding reverberation chambers. Theoretical aspects of TLM method and its application for electromagnetic fields solution are covered. Some results are presented, considering pre-defined reverberation chambers configurations, highlighting some merit indicators and the main aspects adopted on its simulation.
