TLM modelling of receiving dipole antenna impact on shielding effectiveness of enclosure

Numerical calculation of shielding effectiveness of enclosure with apertures based on EM field coupling with wire structures

“…In [11][12][13] authors have numerically consider the impact of the physical presence of the receiving dipole antenna on the level of EM field inside the enclosure and therefore on accuracy of estimated SE when antenna is used in an experimental procedure. The motivation for this research was that equivalent circuital model presented in [4] provided SE results slightly different from the measurements due, as stated in [4], its inability to include the receiving antenna.…”

“…Due to numerical model ability to account, unlike circuital model, for two-way interaction between EM field inside the enclosure and receiving dipole antenna, we proceed in this paper with using only the numerical model in our analysis of wire parameters impact on the SE. Besides directly sampling the EM field in the space nearby antenna to estimate the SE of enclosure as in [11,12], another way of collecting signal that corresponds to the experimental procedure is also proved to be valid [13]. A current signal can be picked up directly from the antenna and then used to find the voltage induced in the center of the dipole antenna to calculate the SE.…”
