Use of Computational Electromagnetics to Enhance the Accuracy and Efficiency of Antenna Pattern Measurements
<p>The objective of this dissertation is to illustrate that computational electromagnetics can be used to improve the accuracy and efficiency of antenna pattern measurements. </p> <p>This can be accomplished in many different ways, such as moving a single probe over the measurement plane to …

Emission source microscopy for electromagnetic interference source localization
… with multiple sources, it is often difficult to localize the sources of radiation. Near-field electromagnetic scanning is used often for root-cause diagnosis by determining field distribution close to the PCB. In the near-field, the evanescent waves are dominant, which may lead to the …

Radio frequency interference (RFI) modeling of complex modules in mobile devices and system-level modeling for transient ESD simulation
… for phase resolved scanning over random fields generated by multiple uncorrelated stochastic sources. This method can separate the field contribution of each noise source and resulting field patterns as if the out-of-interest sources were turned off. The scanned data can be used for …

Near-field scanning study for radio frequency interference estimation
… discusses the novel techniques using near-fields scanning to do radio frequency interference (RFI) estimation. As the electronic products are becoming more and more complicated, the radio frequency (RF) receiver in the system is very likely interfered by multiple noise sources …
