Ok.  The beginning of understanding comes when you consider a charged
spherical antenna on a typical Tesla coil.  What happens when you have a
charged antenna?  The antenna wants to discharge right?  So the beginning
of current manifests as an electro-magnetic wave begins to propagate along
the wire spiralling down the coil.  But what also happens at the exact same
moment the discharge begins?  You get voltage drop.  As soon as the voltage
begins to drop, the change in potential is "felt" by the topmost winding of
the secondary.  This is a capacitive effect just like how change in voltage
propagates across a capacitor plate.  Now this first winding suddenly has a
potential change because of it being influenced by the voltage drop in the
tower.  This is the beginning of the LMD wave.  Consider that the change in
potential on the first winding will immediately influence the next winding,
and then the next, and the next.. and so on... all the way down.  This is
the LMD wave propagation.  And this thing moves faster the actual
"electricity" (which is really a magnetic wave) moves through the wire.
This means that the LMD wave will reach the Earth before the TEM (the
electricity as we are taught to think of it) reaches the earth.

The result is very compable to super sonic jet.  Around Einstein's time
people thought that you couldn't travel through air faster than speed of
sound.  That is also why Einstein was following the same mentality.  But
what happens now when we go faster than speed of sound?  The jet is like a
wave propagating through air, yet the effect of the wave trails way
behind.  Similarly in Tesla coil, LMD wave can propagate faster than charge
carriers are able to respond with "current flow".  LMD wave always
accelerates out ahead of the TEM wave, leaving the TEM wave behind.  Hence,
you have two frequencies.  And the LMD wave is normally lost because we
tune our devices to the TEM frequency.

At least this is what Konstantin Meyl  and also Professor Handwerker from
Italy has shown us.  Believe it or don't.  :D
