Art wrote: "Thus if we have a radiator of one WL that is tipped in space and near zero resistance in impedance metric we will then attain a spherical radiation pattern with Poynting`s vector and thus a demonsration of point radiation together with further evidence that radiation is of particle and not of waves." No matter how Art`s words were combined, I don`t see in them any such evidence. Even Art agrees that Maxwell`s equations correctly produce answers to where the energy goes. The 1955 edition of Terman`s "Electronic and Radio Engineering" shows the radiation pattern of one WL of wire in Fig. 23-4 (b) on page 867. It consists of four lobes each making an angle of 54 degrees with the axis of the wire. The pattern deviates from a spherical pattern by a lot. So much for "equilibrium"! Cecil pointed out that in physics, electromagnetic radiation is treated with duality, using either particle theory or waves, whichever is more convenient for the problem at hand. Maxwell solved the problems of radiation using wave equations which are said to be four of the most influential equations in science. "Heaviside said that mathematics was an experimental science. He organised Maxwell's mathematical work into the four equations which we now call "Maxwell's Equations". Maxwell made model of solid etherWhat is Heaviside's model like? On page 864 of Terman`s 1955 opus he writes: "The laws governing such radiation are obtained by using Maxwell`s equations to express the fields associated with the wire; when this is done there is found to be a component, termed the radiated field, having a strength that varies inversely with distance. If Art would just absorb Terman`s chapter on "Antennas" I doubt he would write such nonsense. S* |
