“…A typical frequency range for standard TEM-cells is from 150 kHz to 1 GHz, although the cell can be modified for frequencies up to 2.5 GHz [15]. At higher frequencies, resonance phenomena appear by higher order modes of the electromagnetic wave, making the cell unsuitable.…”

Manufacturing electronic devices requires accordance to the electromagnetic compatibility requirements. Taking into account the growing importance of inductive wireless power transfer at higher frequencies, it is important that one can already early in the design process characterize the emissions. In this work, we describe the experimental methods which could be used for the characterization of as well conducted as radiated electromagnetic emissions of inductive wireless power circuits. We discuss the advantages and drawbacks of these methods and compare them with each other.

“…To ensure correctness of measurements, a single TEM mode has to propagate along the transmission line. With increasing frequency, relevant TE modes (TE 01 , TE 10 ) start to propagate along the line [4]. The cut-off frequency of the TE 01 mode can be calculated according to [4]:…”

“…In the open literature, exploitation of numerical models for the design of TEM cells is described in several papers. The articles investigate the methods for suppressing higher order modes in TEM cells [4], [14]. Numerical methods are used in the design phase to achieve the requested behavior of the TEM cell over a wide frequency range [15].…”

In the paper, a simulation-based design procedure for the implementation of a TEM (Crawford) cell is presented. The empirical approach uses computer simulations carried out in CST Microwave Studio to design the cell that operates in the frequency range from 100 kHz to 400 MHz. Following the developed procedure, the TEM cell was implemented and tested experimentally. The TEM cell can be used for electromagnetic susceptibility (EMS) measurements, where the device under test (DUT) is irradiated by the field in a wide range of frequencies. The DUT is tested to operate without the performance degradation under the influence of electromagnetic disturbances. In addition, the cell can be used for electromagnetic interference (EMI) measurements focused on interference emissions generated by the DUT.

Resumo 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).
