This is an article I wrote several years ago but have since found no good venue for publication. If someone can recommend one, please contact me. Because I think it may be useful I’m making it available.
The common theory for coaxial line which has its basis in a circuit model by Heaviside from the 1880's is at odds with the physics expressed by Einstein and Schelkunoff. Previous articles have shown theoretical results and practical applications from a newer understanding. This article further discusses some of what we've missed, why we've missed it, and why it might matter.
Here are the Text of the Article and Accompanying Figures .
An October 2016 Pacificon Presentation, SWTL Summary and Demonstration which is a sort of summary of the SWTL technology, demonstrations and other activities on these pages. Please note that this is NOT "G-Line" as described by Goubau (which required slowing the wave down) nor is it the same as what Tesla described.
2nd Demo -100 meter SWTL (view on YouTube) - transmission/recovery of 144 MHz power guided along a single .013" (0.32 mm) conductor transmission line (SWTL) at 144.5 MHz using very light weight launchers. This system can be used to power quadcopters/aerostats for continuous flight while providing extremely low loss connection to elevated antennas - enabling quickly deployable, long range, very high bandwidth communications systems for Internet, emergency and other communications.
Power transmitted over a single 0.32mm wire (view on YouTube) 1st Demonstration - transmitting real power across a short single .013" (0.32 mm) conductor transmission (SWTL) at 146 MHz.
2m Halo vs. 4 el. Yagi Pictures and results of a balloon-supported 2m halo antenna at 160' AGL, fed and tethered by a SWTL, WSPR used to measure and demonstrate 25 dB improvement over a ground-mounted 4 element 2m Yagi.
Pacificon 2011 Antenna Forum, I gave a presentation includes an overview of three different amateur applications for surface wave transmission line, along with a new antenna theory for understanding conventional antennas such as dipoles and monopoles as surface wave devices. All but the first of these, "A Flying Antenna" have been published as a three part series in ARRL QEX.
