Hello, and thank you for your response.
You can find some more information in 'mainstream' physics by searching for 'quantum tunneling'.
Here are some links:

The first link contains quite a few citations.
I agree that academicians are religiously tied to the idea of nothing moving FTL. I'm also familiar with Eric Dollard. I like him very much. If for nothing else, because he is shining new light and new perspectives on long-held (but not necessarily entirely correct) theories of wave propagation.
The idea of the dielectric is very interesting. The question of 'How can we increase the dielectric constant?' is central to the conversation. To do this, we must focus on a 'phase conjugate dielectric'. When we create such a dielectric, the wave propagation distribution efficiency will rise, and this allow for 'faster' travel through the medium and 'less resistance'. The climax form of which is golden ratio optimized, and therefore fractal, distribution of charge/wave activity. The fractal nature of the golden ratio can be seen here:
But to your point, isn't radio a type of EM wave? Since the answer is 'yes', I would propose that we have, in fact, 'sent' an electromagnetic sine wave signal faster than the speed of light.
