Topband: Tree conductivity

[Bob Kupps]

Yes I am no doubt in that group. So do good conductors in the near field re-radiate most of the coupled energy (eg a parasitic element) while poor conductors dissipate it as heat? I would think poor conductors or lossy dielectrics like trees would not couple much energy from the field, whether they re-radiate it or dissipate it.

What we have is an inability to understand the difference between very good conductors, poor conductors,  and or lossy dielectrics. We'd have a difficult time powering something through saltwater conductors, or having resonance effects with saltwater jets at low frequencies. At the same time, even crummy soil has a profound effect on EM fields and other things when cross sectional area is large enough.

There is a danger that people will not understand the big picture, and write more seawater antenna or tree antenna articles.
