... John could well be correct as certain assumed conditions(assumptions) were set over and above Maxwell's laws prior to the program being computed ! These programs are generally used to determine the functions of planar antennas and the like that do NOT meet the conditions implied in Maxwell's laws. One condition implicite in all the laws of the masters is that Newtons laws with respect to equilibrium must be observed, which rules out such arrangements as the Yagi. This is not to say that Maxwell's laws are used incorrectly in antenna programs,only that it is usually used outside its intended usage where acountability of all vectors are not accounted for, which thus provides aproximations Close enough for horse shoes and lemmings but not for the pursuit of science along the lines intended by Newton and others. Best regards Art Unwin KB9MZ Art: With so many fools (indians?) after my scalp, I am lucky to remain on the square I occupy ... these fools attempt to drag us back to dark ages ... Regards, JS |
