The only reason for Maxwell model is the light polarisation. In his era the polarisation was explained with transverse waves. Now we know (from Clark) that the apparatus is polarised not waves. Regards, S* i knew getting you and art together would be interesting... good for a whole evening full of laughs! the waves must be polarized to interact as observed with polarized antennas. But here are the two possibilities. 1. The dipole radiates the transverse wave from centre, 2. The dipole radiate the two COUPLED longitudinal waves from the two ends. In the both cases the antennas (emitting and receiving) must be parallel. Which place radiate the radio waves? S* the whole antenna radiates. But what radiate? Magnetic whirls or pressure-like electric wave? S* magnets don't whirl and 'electric waves' are not like pressure... they magnetic and electric field vectors are at right angles to each other and the direction of propagation... both the electric and magnetic components are needed for propagation... you can't have one without the other. |

It's hard to tell, but he's probably referring to the curl of a magnetic field which he obviously doesn't understand. The idea of a "pressure-like electric wave" is pure fantasy. 73, Tom Donaly, KA6RUH |

Where did you get that idea from? Art |
