New correlation algorithm between FAC and OATS/SAC FAC与OATS/SAC之间新的关联算法

The approach is to model the EUT as an equivalent set of multipoles. Assuming the EUT is electrically small, only the initial multipole moments, the electric and magnetic dipole terms, need be retained. A sequence of FAC measurements is then used to determine the equivalent EUT dipole moments and relative phases. The dipole model then allows one to simulate the radiated emission from EUT over a ground screen. Thus, emission measurements over an OATS as called for by various standards may be simulated. Such equivalent dipole modeling of an unknown source object has previously been successfully developed for the single/double port TEM waveguide. This paper reviews the basics of the multipole model as it relates to FAC, details various measurement schemes appropriate to FAC, and presents the results of measurements at both FAC and SAC in order to verify the proposed correlation algorithm","PeriodicalId":272545,"journal":{"name":"2003 IEEE International Symposium on Electromagnetic Compatibility, 2003.

In this paper, we investigated the quantitative relationship between the frequencies of peak emissions radiated from a PCB and the resonance resistances of the PCB impedance from measurement and finite-difference time-domain (FDTD) analysis. As a result, we found that the ratio of squared electric far-fields at the PCB resonance frequencies corresponds to the ratio of radiated resonance power. This finding leads to the conclusion that the radiated peak emission frequency can be predicted from PCB resonance resistances and the internal resistance of the PCB excitation source","PeriodicalId":272545,"journal":{"name":"2003 IEEE International Symposium on Electromagnetic Compatibility, 2003.

Results of the analysis can be applied to calculating screening effects of conducting walls and housings.
