: Once you understand the difference between standing waves, (which has no real power itself but which stores the reactive VA power into that power which is is eventually dissipated in "radiation resitance" dissipating into free space as radiation power), and traveling waves, which do have real power that is also disspated into that same type of radiation power through the radiation resistance, an interesting question becomes "what is the nature of this so-called radiation resistance which dissipates the power of a forward wave or the stored power in a standing wave?". We feed power into the antenna as electric current and then it exits the antenna as radiation. Maxwell's equations (in spite of what art theorizes) says that the power has been converted to an EM wave. So, electric current, which is not an EM wave consisting of photons and propagating into space, is converted into a different form of radiation energy that IS an EM and does consist of phtons and waves. When this conversion occurs and energy is transmitted into free space, we attempt to quantify this net loss to our generator with familiar terms, i.e. current or voltage dissipated into "radiation resistance". However, we all know there is no actual physical component known as a radiation resistor. Conceptualizing how this power conversion works goes back to maxwell: "why" is there a time varying EM magnetic and electric field (external waves and photons) generated by the flow of current? Well, it could be described as nature's tendency to maintain equilibrium. If a change is made to a conductor by putting a current through it, nature "objects" and fights back by setting up an EM wave that tends to cancel out the incoming current pulse. But no matter what, I will always easily have enough energy in my forcing function (current or voltage) to overcome nature's objection and send a net outflow of energy occuring as radiation theoretically equal to what I inputted. Well put, Daniel. One of the biggest difficulties I have with Art's theories is that I can't get my head wrapped around them. I know he unfortunately has a few physical challenges that make his postings a little difficult to go through at times, so I re-read them often to see if I can glean something out of them. But whereas I have great difficulty with some folks posts. I understand everything you wrote. - 73 de Mike N3LI - |
