Technology

E-Line makes use of a newly discovered mode of propagation that is supported by a single conductor. Unlike traditional transmission lines where E and H fields are perpendicular to the direction of propagation between two conductors.  E-Line is a surface wave transmission line (SWTL) operating on a single conductor where the E field has a  longitudinal component.  This unique technology allows unprecedented transmission line characteristics even when coupled onto standard, utility-grade power lines.  Compared to traditional transmission line techniques, E-Line has excellent frequency coverage (20 MHz - 20 GHz), much lower attenuation than coaxial cable, very flat group delay, and low distortion.  An introduction to the theory, measurement, operation and application of this mode of propagation to practical systems:  Introduction to the Propagating Wave on a Single Conductor
