ABSTRACT
An attempt was made to match the output of a model consisting of a network of segmented cables with the response experimentally observed on cables at the EMPTAC. The model allows the network to be driven by arbitrary fields at each segment. It yields current or voltage at any place on the cable that may be directly compared to the measurements made by a network analyzer. The line response and drivers are coherent over space and frequency at low frequencies. To mimic the random behavior seen in the EMPTAC data, the excitation over the segments and from one frequency to the next becomes Jess coherent at intermediate and higher frequencies. An electromagnetic enclosure driven well into the overmoded regime will have a power-flux distribution that is chi square with two degrees of freedom if the observer is fixed and frequency is swept or if the frequency is fixed and the sensor is translated or rotated.
