Determining Total Gain of an Antenna

Cecil, I am questioning the bundling of radiation with respect to Poyntings vector and the polarization of the far fields. Ofcourse any mathematical analysis must start with the application of current and resulting movement of flux ala Pointings vector. However I have yet to see an explanation how this mathematical function is impacted upon by the polarisation desired. Even if this is a misinterpretation of what is in the books the poster is at least entitled to a explanation of the effect of circular polarization and how this impinges on Poyntings vector in a mathematical sense. How else can we attract newbies to the hobby? I wouldn't worry about it, Art. The poster wanted to know how to properly combine e-fields in order to calculate the induced voltage on an antenna. I'm sure by now he's figured out that asking a mathematics question on a ham radio newsgroup is a waste of time. I expect the answer would be found in Jackson. 73, ac6xg |
