Distributed capacitance and antennas
How does distributed capacitance harvest the energy given
in sino soidal form and later release it in the same form that it was harvested in? Same question, but now look at distributed inductance and how that works! Distributed resistance is easy, it changes the energy to heat, stores it and releases it according to its time constant but the books don't tell me.about the other things! Like the time constant of distributed capacitance Art |

Go away Richard. You never answer questions you only jeer people. If you don't answer the Wood question directly instead of going all over the place I will have to let your posts slip by me You can always start your own posts you know instead of looking for somebody to jeer at! That would be a good way of establishing relationships with like wise thinking people to replace that guy in S America Art |

Sounds like you should discuss those personal issues with your chaplain and stick to technical topics quoted above. This isn't rec.radio.ann.landers. 73's Richard Clark, KB7QHC |

Does distributed store energy like other capacitors or is it an animal by another name? Does it store photons for later distribution of radiation? Do photons eat the electrons while they are being stored by the capacitor Do the electrons jump up and down because they know an inductance is ahead? These questions are very important in determining what radiation is all about. And yes I hear waves are often mentioned. Is this the three dimensional wave that is created in the pond when the static particles fall off the antenna in a circular type pattern? Antenna books say the pattern is a figure eight! How can that be? When the energy removes itself from distributed capacitance do the photon march along the antenna in an orderly fashion? or do they rush out as if the movie in the capacitor is over? Last of all has anybody seen a photon and photographed it? I suppose if you believe in ghosts then you could well believe in photons that float in the night. You can't see them but there really is a chill in the air. So back to the original question, What does distributed capacitance do with the oncomming sino soidal wave? Does it let it through unharmed so that we have a time varience that is needed for radiation per the radio books? Art |

"Same question, but now look at distributed inductaance and how that works!" On page 2 of Terman`s 1955 opus is written: "The strength of the wave mmeasured in terms of microvolts per meter of stress in space is also exactly the same voltage that the magnetic flux of the wave induces in a conductor 1 m long when sweeping across this conductor with the velocity of light." Remember reciprocity and the fact that only a perfectly matched antenna can extract as much as half the power in the wave. The antenna`s radiatiation resistance acts as a Thevenin source when receiving and reradiates the other half of the power received but not delivered to the load. The description of magnetic flux inducing signal into a receiving antenna may be the cause of describing transmitting antennas as creating from current in the wire a magnetic flux around the wire which almost simultaneously produces an electric field which almost simultaneously produces a magnetic field ad infinitum.
