This research concentrates on developing a complete theoretical tool to analyze the electronic mode-stirred reverberating chamber. A 2D modeling of the EM fields is performed, which can then readily be extended to a 3D analysis of the cavity. The finitedifference time-domain (FDTD) method is implemented to discretize the Maxwell's equations. With our newly proposed method, the electromagnetic-field characteristics can be easily studied inside the reverberating chamber under a realistic circumstance, thus opening doors to the analysis of a large spectrum of problems related to both commercial and military applications.

“…The main simplifying assumptions (linearly copolarized AUT and FP) can be more or less easily relaxed at the expense of minor formal complications which do not alter the main conclusions. On the basis of these preliminary results, the possibility of performing cheap, simple and reliable in situ antenna measurements using, e.g., flexible conductive thin-film deployable/inflatable enclosures with air-blow stirring [20], [21] is envisaged. …”

“…A receiving discone antenna [14] had a vertical polarization, minimizing the line of sight (LOS) component. The second analyzed chamber, the VIRC, similar to the one presented in [15], is shown in Figure 2.3. Its dimensions are 150 cm x 120 cm x 100 cm, making it only slightly smaller than the used RC.…”

SummaryThe phenomenon of resonating electromagnetic (EM) fields has been commonly and successfully exploited in reverberation chambers (RC) for the purpose of electromagnetic compatibility (EMC) testing, as well as modeling multipath environments. An RC is designed to maximize the amount of reflections while minimizing the losses, thus creating a statistically uniform, isotropic, and randomly polarized field. Due to the desired very high complexity of such a field, its description is best done statistically. Although largely successful, the currently used statistical models allow for a certain degree of freedom, especially with regard to defining the extreme field strengths, which are also the main cause of electromagnetic interference (EMI). Furthermore, some actual multipath, enclosed environments such as airplane fuselages, ships, or even building interiors, can unintentionally possess the ability to create enough strong reflections so that the resulting resonating EM field within them resembles the field inside a dedicated RC. Those reverberant environments (RE) can therefore utilize the methods and techniques similar to the ones used in laboratory conditions. Due to the very high complexity and diversity, resulting in increased difficulty of both numerical or analytical description of the REs, the analysis performed throughout this work is mainly experimental. Such an approach allows to bypass the often unreasonable or too generalized assumptions of the available models while utilizing purely empirical data.The initial step made in this thesis focuses on introducing REs as environments sharing multiple aspects of EM field shaping with RCs. The experimental analysis has been performed on two example REs by means of quality factor (Q-factor), insertion loss (IL), as well as goodness of fit (GOF) tests. The results, although highly variable with frequency, indicate a possible similarity to a referential RC analyzed alongside. Furthermore, due to the difficulty of collecting large amounts of data and parameter isolation in the REs, two dedicated chambers: a classical RC and the vibrating intrinsic reverberation chamber (VIRC), have been analyzed as candidates allowing to simulate an RE in laboratory conditions. By the means of Q-factor, k-factor, GOF, as well as number of samples, related to field repeatability, it has been shown that the VIRC provides substantially better conditions for the given purpose.The search of maximum field strengths in reverberant environments has been performed by exploiting the capability of the VIRC to efficiently generate large amounts of independent samples. Performing 1-hour long measurements in the VIRC allows to obtain the desired results with very high repeatability, while giving space for parameter isolation. The first hypothesis states that the maximum-to-average (max/avg) electric field ratio depends on the losses of the environment. The measurement campaign performed to test it consisted of multiple setups with highly spread Q-factors, additionally creating a link between...
