Stupid question about longitudinal EM waves

I was never interested in EM field theory. I made that exam decades ago, and with great trouble. This longitudal/scalar electromagnetic wave scientific crackpotism I came across recenty ( provoked some questions anyway.

[ul][li]Are longitudinal EM waves theoretically possible at all (I'd say they aren't, but I'm not too sure)?[/li]
[li]How does EM field between infinite capacitor plates looks like? Where does magnetic component (if any) point to?[/li]
[li]Or alternatively- how does EM field around electrically charged, periodically inflating and deflating sphere looks like? Again- where does magnetic compnent point to?[/li][/ul]

Suggestion: A generic definition of "longitudinal wave":
A wave in which the direction of displacement at each point of the medium is the same as the direction of the propagation.

I know 1st hand, that point 3 from is false. Maxwell's EM theory, and Einstein's relativity theory fit together rather nicely. There exist very simple, and elegant way to derive Maxwell's magnetic field equation from the electric one, using only special relativity theory. The rest of it looks like a horsetwaddle, at least at a hasty glance.

Ummm... OK, let me click around your links little bit ... Tesla Howitzer!? Oh my goodness!

And what about this one ? Ok, a little click here, a little click there, and ...

"Tesla's waves were actually these THETA-field scalar waves. As such, they were fundamentally different than ordinary electromagnetic waves, and had entirely different characteristics, just as Tesla often stated. E.g., a Tesla wave can either move spatially, with time flowing linearly; move temporally only (sitting at a point and waxing and waning in magnitude -- but changing the rate of flow of time itself in doing so, and affecting gravitational field, fundamental constants of nature, etc.), or move in a combination of the two modes. In the latter case, the Tesla wave moves in space with a very strange motion -- it oscillates between (1) spatially standing still and flexing time, and (2) moving smoothly in space while time flows smoothly and evenly. I.e., it stands at one point (or at one columnar region), flexing for a moment; then slowly picks up spatial velocity until it is moving smoothly through space; then slows down again to a "standing column," etc. This is Tesla's fabulous "standing columnar wave. Another wild characteristic of the Tesla wave is that it can affect the rate of flow of time itself; hence it can affect or change every other field -- including the gravitational field -- that exists in time flow. It can also affect all universal constants, the mass of an object, the inertia of a body, and the mind and thoughts as well! "

Mind and thoughts indeed! (-: :p

Oh, well... I guess I got the point. Infinite capacitor plates are not feasible, and electric field around charged inflating/deflating sphere does not change. Right?
