Statistical characterization of multiconductor transmission linesilluminated by a random plane-wave field

摘要

This work addresses the problem of field coupling tomulticonductor transmission lines (MTLs) by means of a statisticalapproach. Currents induced in the MTL loads are regarded as randomvariables, depending on random amplitude, polarization, and direction ofincidence of an offending plane wave. The aim is to identify somestatistical properties of the current magnitude in the line loads.Influences of the MTL geometrical parameters and load configurations onthe statistical properties of the currents induced in different MTLwires are investigated. In particular, a bundle- and a bus-likeconfiguration are analyzed and compared from the point of view ofexternal susceptibility. For low frequencies, the consistency ofstatistical estimates is supported by analytical considerations
