but of course you can't radiate without generating a magnetic field and any current produces a magnetic field so everything you are saying is junk. Here's a quote from "Fields and Waves ...", by Ramo and Whinnery: "A perfect conductor is usually understood to be a material in which there is no electric field at any frequency. Maxwell's equations ensure that there is then also no time-varying magnetic field in the perfect conductor." -- 73, Cecil, w5dxp.com |
