S* "Like sound " antennas are in sale for ages. If Art's are or will be - I do not know. I am not an expert. (I have trouble with understanding Art's idea - he is using very sophistcated terms). S* show me the equations for modeling a dipole radiation pattern using sound in free space, be sure to account for polarization. I have something like this:http://perg.phys.ksu.edu:80/vqmorig/...ave/Slit/vq_mw... See also 1864 in:http://online.physics.uiuc.edu/cours.../Lecture_Notes... Transversal wves have no sense. The equations are usefull for teaching the math. right, read this carefully from that 1864 note: *'the requirements of his mechanical model keep him from finding the correct boundary conditions, so he never does this calculation'. This is just one of the basic shortcomings of using a mechanical analogy, you can not satisfy the electric and magnetic field boundary conditions that the final version of his equations handle properly. In science area are scientists and teachers. All scientists know that electricity, magnetism and gravity are the same. Teachers know that the three must be taught seperately. Are you a student? while some basic effects like the interference patterns can be duplicated for both longitudinal and transverse waves, they are not interchangeable in all cases and trying to do so will only lead to absurd things like electrons jumping off antennas or the need for an aether to transmit em waves. Maxwell's model is for the aether. But with the two substances: magnetism and electricity. Your antennas have the blunt tips to prevent the "jumping off ". The alternate voltage in the ends create the oscilation of electrons in neighbourhood . Electrons in space are detected. So they are the aether. Do not you hear on Dirac electron see? S* no, i am not a student, i am an engineer by training and scientist by title. where in maxwell's equations is there an aether? not all antennas have blunt tips, and electron's don't just 'jump off' an antenna. no, just because there are electrons in space doesn't make that an aether. there are electrons flowing in vacuum tubes, that is a current, not an aether to carry em waves. |
