Interferência eletromagnética
Abstract in Portuguese
O presente trabalho apresenta resultados de simulações numéricas de uma célula TEM assimétrica aberta com o objetivo de otimizar seu desempenho. Entre as otimizações, é investigado o uso de fendas resistivas para estender a faixa de frequência de operação da célula. Além disso, otimiza-se o casamento de impedância entre o conector coaxial e a célula TEM. São apresentados os resultados medidos da transição otimizada em laboratório. Foi construída, também, uma célula TEM assimétrica e seu desempenho foi verificado em laboratório, obtendo-se uma perda de retorno maior que 10 dB na faixa de operação (30 MHz a 3 GHz).

Abstract in English
This work presents numerical simulations of an open asymmetric TEM cell in order to optimize its performance. Among the optimizations, the use of resistive slots to increase the bandwidth of the TEM cell is investigated. Furthermore, the transition between the coaxial connector and the TEM cell is also optimized. Measurements of this optimized transition were performed in laboratory validating the simulations. A prototype TEM cell was built and its return loss was verified to be above 10 dB over its entire band of operation (30 MHz 3 GHz).
