This is an article written
for engineers to help them gain
engineering intuition for practical EM field calculations. The curvature Hammond mentions is not part of the real-E&M, it's part of the maybe-this-helps-your-intution. There are many such intuition-helpers in computational E&M. For example, a long solenoid is not
really a pair of magnetic monopoles, but engineers are welcome to (and frequently do) pretend that it is.
A photon is essentially a singleton electromagnetic wave which is a spatial curvature propagating at c.
Are you utterly unable to tell the difference between Farsight-ism and mainstream physics? This "spatial curvature" is something
you made up. That's why you can't find it in Jackson or Purcell or Griffiths, and that's why every physicist on this board has laughed at you for claiming it.
Did you
forget making it up? I guess that happens sometimes. Like, I'm cleaning out an old file cabinet, and come across some calculations, and I say "This is interesting, whose are these?", and after reading them I discover they're mine. Is that happening to you? Are you discovering
your own ideas in file cabinets, forgetting whose they are, assuming they're well-known physics insights, and citing them?
All electromagnetic waves share the same action h, which has the dimensionality of momentum x distance. You can see a trace of it in
pictures of the electromagentic spectrum. All the waves are the same height.
Literally LOL. That "trace" represents an electromagnetic field magnitude, not a distance. The field can assume any magnitude whatsoever, and its units are volts-per-meter. When someone wants to draw a cartoon of an electromagnetic field, they draw an
arbitrary sine wave and change the height until the cartoon is pretty. It has nothing to do with physics.
And: if you're hoping that the
field magnitude magically works out to be a constant after you quantize photon energies? Like, "each photon, no matter the wavelength, always has the same (something proportional to field)?" Nope, that's not true either.
