Here is a short article on the concept:

http://hamchatforum.lefora.com/2009/11/13/hf-radio-propagation-and-su...

Here's a shorter one:

In order for signals to refract (be bent back toward the Earth) the
ionosphere needs ions. These are produced when UV radiation interacts
with the atmosphere. UV radiation comes from Sunspots.

And nobody can figure out what causes the sunspots. Unknown.

Although the details of sunspot generation are still a matter of
research, it appears that sunspots are the visible counterparts of
magnetic flux tubes in the Sun's convective zone that get "wound up" by
differential rotation. If the stress on the tubes reaches a certain
limit, they curl up like a rubber band and puncture the Sun's surface.
Convection is inhibited at the puncture points; the energy flux from the
Sun's interior decreases; and with it surface temperature.http://en.wikipedia.org/wiki/Sunspot

Yes,it is a scientific research,still in progress !

Well, they don't know for sure, but here is the very latest theory:

Convection is inhibited at the puncture points; the energy flux from the
Sun's interior decreases; and with it surface temperature, thus creating
what we call sunspots.

This theory has been pretty much proven using computer simulation.
Plasma is a state they didn't teach me in high school.

Plasma antenna is a new gadget. Should work well in the HF region. So
I heard.

More doable may be a 'Maser' Antenna
{Vertical 'Energy Beam' Antenna}

Provided you don't end up with an operational
Particle Beam Antenna that knocks out Aircraft
flying overhead or Satellites passing by . . .
