1.There is no standing wave, it is an abstraction. Look at the formula for
reflection coefficient, the only terms are Zf and Zr. 2. The standing wave does not cause IR losses, the losses are because of the increase of reflected current. We measure that increased reflected current and from it create a ratio to the forward current and describe it as a standing wave ratio. 3. To argue which way a ratio goes is pointless. 4. The jump rope example shows the forward and reflected wave only. One may observe the constructive and destructive resultant waves. One can NOT see a standing wave, whereas one may be computed from the observations. 5. Set the reflected current equal to the forward current and the field changes from electrical to magnetic twice a second. A pure observable non moving standing wave, some call that resonance.

Current that doesn't move means that dQ/dt equals zero. Hint: current cannot exist without movement. Even DC current cannot stand still. AC/RF current is even worse for your illogical premise. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
