The mathematical model of spurious electromagnetic emission of local informative network, the Caushy problem for 3D Maxwell equations based on is represented. The techniques of input data assigning are investigated. The results of model calculation in the formulation of problem, which takes into account screened source and receiver of informative signal as well as ground connection, are represented. The space-temporal characteristics of electric field distribution took a possibility to draw a set of conclusions relative to the emission droop and the main sources.
