Investigation of RF coupling and radiation leakage parameters of some typical junction box circuitry configurations

The objective of the study, composed of two experiments, was to collect baseline data that could be used to determine the degree of electrical coupling between circuits and RF leakage of some common junction box configurations. These experiments assume an empirical approach for measuring RF coupling and leakage parameters due to the complex geometry of the junction box circuitry configuration. The report presents a method for measuring these distributed parameters in order to calculate the values of amplitude and phase coupling for this simplified case from the model. These values are compared to the experimental measurements for the model to verify the experimental procedure. The results of this theory are then extended to the more complex structure of the cabling configuration within the conduit and the junction box.
