Why are you having difficulty with that concept from page 388 of "Optics", by Hecht, 4th edition? *** 2 *** Again, reflected power doesn't flow so it doesn't go anywhere. Until you understand that simple fact of physics, further discussion is unlikely to yield valid results. "Reflected power that goes" is only one of your many conceptual flaws. So your first logical step would be proving that reflected power actually flows. After you do that, we can continue to your other conceptual flaws. Paragraphs 1 and 2 appear to declare exactly the opposite behavior for energy (power). Paragraph 1 is about energy and doesn't mention power at all. Paragraph 2 is about power and doesn't mention energy at all. Energy is as different from power as length is different from velocity. Do you also get length and velocity confused? Is there some subtle re-definition going on to allow "redirected back toward the load" and "it doesn't go anywhere" in the same message? Here's a quote from my web page: "The term "power flow" has been avoided in favor of "energy flow". Power is a measure of that energy flow per unit time through a plane." The dimensions of power flow would be watts/sec. I'm not sure what quantity watts/sec would represent or where it would go. -- 73, Cecil http://www.w5dxp.com |
