<DIV>The gradual change from 90 degree phase shift you suggest ‘must’ happen
isn’t evidenced as far as I’ve found except in specific circumstances in diffuse
fields where it’s evidenced by birefringence (or to be precise
multirefringence). But there is another option which is consistent with
evidence. The whole change from near to far field, unexplained by Maxwell (or as
the transform from from Fresnel to Fraunhoffer) Can happen far more abruptly and
may be very important in advancing understanding generally. It has parallels in
both Special Relativity (The ‘Lorentz transformation’) and Quantum Mechanics
(the unexplained 90 degree phase shift in the sine curve pairs).</DIV>
<DIV>One simple mechanism, lets say at the surface of an antenna moving through
a field or similarly a planet moving through a heliospheric rest frame (is that
a dense ‘surface’ electron layer is propagated (as found in surface fine
structure & shocks), which a field particle absorbs EM radiation and
re-emits in it’s OWN LOCAL centre of mass rest frame. That gives a ‘Discrete
Field’ model of local physics with physical transitions between. Now do what
Maxwell recommends and use thought to find implications. Firstly Einstein’s
final 1952 concept of inertial systems as ‘fields in motion within fields’ makes
sense, then you should find all else falls into place. A bit shocking perhaps
but if you do what Maxwell suggests it’ll work.</DIV></DIV></DIV></BODY></HTML>
