Hi, > If I look at the Maxwell equations, it appears however, that at the > maximal change of H, induced E is largest, and at maximal change of E, > the induced H. So should not H peak, when E goes though zero? This This is not quite correct. Maxwell equations say that at maximal change of E the rot H is largest, not H itself. And large rot H does not mean that H must be large. Please, have a look at the sixth and seventh images on the webpage: http://www.math.umn.edu/~nykamp/m2374/readings/divcurl/index.html which show a vector field which vanishes on an axis but its rotation is not null. > Obviously something is wrong with my picture. Can anyone shed light > on the phase relation between H and E in a wave packet? J.D. Jackson, "Classical Electrodynamics", second ed., equations 7.1-7.11. cheers, Andrzej Olczak
