Similarity Criteria of EHF Physical Model of Long Distance Transmission Line with Plate Phases

open access: yesActive and Passive Electronic Components, 1988
Carson's equations for computation of frequency dependent parameters of overhead transmission line are modified. The earth is considered to be homogenous. The optimal required number of terms of Carson's series for applications on computer is determined.
