The nature of Free Space (Once called, "The Lumeniferous Aether")
"gareth" wrote in message ... "Wayne" wrote in message ... Well, I don't know what you are calling "retarded potential". It is the term for the electric potential that must have existed on an antenna when analysing the radiated signal at some distant point. It is termed, "retarded" because the radiation originated at some time in the past. OK now I know. I hadn't heard the term before. But, how about my question? " if the radiated power is equal for two different antennas, why would the field strength be different, except as related to pattern differences?" The radiated power just is spread out differently. |
