while looking into huygen's principle i found a site that showed its just another way to look at waves in 1\3\5\...odd dimensions.
but i bumped into this:
anyone knows what this theory is, and where could i find some mathematical info on it?
but i bumped into this:
i wanted to know more about this wheeler theory, i tried googling for it, but couldn't find more then 10 lines about it...The Huygens-Fresnel Principle is adequate to account for a wide range of optical phenomena, and it was later shown by Gustav Kirchoff (1824-1887) how this principle can be deduced from Maxwell's equations. Nevertheless (and despite statements to the contrary in the literature), it does not actually resolve the question about "backward" propagation of waves, because Maxwell's equations themselves theoretically allow for advanced as well as retarded potentials. It's customary to simply discount the advanced waves as "unrealistic", and to treat the retarded wave as if it was the unique solution, although there have occasionally been interesting proposals, such as the Feynman-Wheeler theory, that make use of both solutions.
