Abstract in Portuguese
O presente trabalho de Mestrado tem por objetivo analisar a utilização de célula TEM (transversal eletromagnética) para o estudo prévio de Imunidade Eletromagnética de pequenos equipamentos, a baixo custo. Descrevem-se a construção da célula TEM utilizada e sua caracterização (experimental e computacional) para uso em uma faixa de frequências de até 200 MHz. Medições em câmara semi-anecóica e simulações computacionais são utilizadas para validar o emprego da célula. Para ilustrar a aplicação do procedimento, é analisada a eficácia de algumas configurações de blindagens visando otimizar recursos de projetos para atendimento às normas de compatibilidade eletromagnética.

Abstract in English
The purpose of this Master thesis is to analyze the use of TEM (transverse electromagnetic) Cell for the previous study of Electromagnetic Immunity of small equipment, at low cost. The construction of the TEM Cell and its characterization (experimental and computational) for use in a frequency range of up to 200 MHz are presented. Measurements in a semi-anechoic chamber and computer simulations are employed to validate the use of the Cell. In addition, as an application example, the effectiveness of different shielding configurations is analyzed in order to optimize design resources to meet electromagnetic compatibility standards.
