“…With the rapid development and wide use of electronic information systems, more and more attention has been attracted to electromagnetic compatibility (EMC) features due to the complex and poor electromagnetic environment in these structures [1][2][3][4][5][6]. Generally, these electronic structures include antennas, transmission line networks, terminal circuits, etc., and EM interaction is very complex.…”

Abstract-A novel field-line-circuit hybrid algorithm based on finite difference time domain (FDTD) method is devoted to predicting the electromagnetic responses of transmission line with multi-ports network in a shelter in this paper. The full wave FDTD method, transmission line FDTD method, and the modified nodal analysis (MNA) are combined to be compatible with the multi-level electromagnetic (EM) coupling progress of the electromagnetic interference (EMI) problem. The proposed method divides the EM couplings among the spatial EM fields, antennas, transmission line networks, and terminal circuits in some typical electronic systems into different levels with appreciate simulation techniques used. The accuracy of the hybrid method is verified by comparing the terminal transient voltage responses of transmission lines with the results obtained by PSPICE, and good agreements are achieved. Numerical calculations are further performed to show the terminal coupling voltages and currents, and the effects of incident directions and polarizations of the illuminated electromagnetic pulse (EMP) are both taken into account.

“…Considering that the OATS is properly constructed, some of the great advantages of open field tests compared with anechoic and semi-anechoic chambers are the low cost of measurements (one-time costs of about five-hundred thousand Dollars) and the ability to obtain accurate measurements [8]. Table I show some latest relevant papers (on the OATS subject) published in the databases of the IEEE during 2013-2017 Aug. 2016 [13 ] A Fast Way to Accurately Calibrate Tunable Dipole Antennas at VHF Jun. 2017 [14 ] The article [9] focuses on the phase center determination for broadband wire-element EMC antenna.…”

“…Environments" [13] promotes the use of prediction methods as an alternative tool for evaluating and managing electromagnetic compatibility (EMC) in hospital environments. Radiated emissions made from medical apparatus are modelled based on open area test site measurements, and they are useful to numerical simulation using the transmission line matrix method (TLM).…”

“…Radiated emissions made from medical apparatus are modelled based on open area test site measurements, and they are useful to numerical simulation using the transmission line matrix method (TLM). The TLM method is implemented to cover not only the multipath effects caused by obstacles but also the combination of all diverse sources on the environment under test [13].…”

This article presents a set of measurements and simulations that evaluate the technical feasibility of a Compact Open Area Test Site (COATS), for the frequency range of 200 MHz to 2 GHz. Its main goal is to provide shielding effectiveness measurements. The described test setup is used for the tests in both semi anechoic chamber and COATS. These experimental and computational results offer orientations and guidelines about the best method to measure radiated emission in a COATS. These measurements results can be quantified through the Feature Selective Validation technique.

“…Além disso, permitiu a caracterização dos EEM quanto à emissão de perturbação eletromagnética para manutenção e proteção do ambiente, e quanto à imunidade eletromagnética para estimativa do risco de interferência. Os resultados obtidos são mais assertivos e objetivos quanto ao gerenciamento de risco comparados a trabalhos que apenas avaliam os níveis de perturbação eletromagnética em hospitais sem identificar a necessidade de tomada de decisão (VALENTE et al, 2016e ARDAVN et al, 2015.…”
