[EMC]A Hybrid Electromagnetic-Circuit Method for Electromagnetic Interference Onto Mass Wires

A current decomposition method is proposed for the ,$7LMTVDrE  
analysis of field coupling to mass wires near complex structures. }=;N3Q" #y  
The foremost attribute of the method is the decomposition of the ]={:VsnL  
current on each wire into push–pull and push–pushmode currents. (Q\QZu@  
The former refers to the perturbation current accounting for the Fl^.J<Dz  
interactions among the wires within the bundle, whereas the latter .KTDQA

represents the interactions between the mass wire bundle and {Km|SG[-q  
the surrounding structure. Multiconductor transmission line theory C`7HC2Is  
is employed to compute the push–pull mode current by using D("['`{
