“…By increasing the width of the TEM cell w, the operation area was increased as well. The width of the input septum was determined according to [8], and the value was adjusted to achieve optimal results. The height of the TEM cell b was chosen according to DUT size requirements.…”

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.

“…This is obviously not a good choice because suffering from the sun and rain will damage the equipment, and the supply and maintenance are also a great difficulty. Another option is to build an anechoic chamber, whose main function is to build a mono-cone TEM cell with a low reflection [7][8][9]. The shell of the anechoic chamber is a steel plate, which has a strong reflection effect on electromagnetic waves and will produce strong multipath components of multiple reflections.…”

In this paper, a cylindrical trimming method is applied to fit the hemisphere, and the total reflectivity on a certain boundary is analyzed through a series of derivations and calculations. An equation that is used to calculate the reflectivity of the trimming cylindrical anechoic chamber is obtained, and obviously, it has no relationship with the spherical coordinate radius r and can be utilized to optimize the trimming size. The proposed scheme of the non-standard anechoic chamber is proved to be a simplified and effective way to optimize the anechoic chamber. An anechoic chamber is constructed to illustrate the correctness of the theory. The simulation results show that S 11 has achieved good results in most frequency bands.
