So exactly who is being disagreeable? If I were to characterize most of the discussion I've had here, I would say most of it has been spent addressing misunderstandings related to the fundamental behavior of nature. Nope, most misunderstandings are semantic. Most of our arguments have been because you misunderstood what I was trying to say and that unfortunate condition continues. You don't seem to possess the normal human capacity to say, "Sorry, I misunderstood".

Cecil, check this months QST (August 2005) Page 52 - figure 5. It
specifically shows that reflections can totally cancel creating black. "Cecil Moore" wrote in message ... Richard Clark wrote: When the energy available in the first medium, at the second interface, cannot possibly reflect enough of it to the first interface; then no amount of superposition of ALL reflections (and this presumes that the second interface is fully reflecting for these succeeding multiples, an absurd notion in its own right) can exceed that available energy. Yes, this has all been said before, you've found it interesting but not compelling; and yet no one here has offered any way to boost the energy to completely cancel the reflection from the first interface. I have multiple times, Richard. When a 111.1mW wave interferes with an 87.78mW wave, the result is *NOT* a 23.32mW wave. It's the waves that interfere, not the power. 111.1mW - 87.78mW = 23.32mW is superposition of powers and is invalid! Instead of superposing powers, the equation you need to use is the power interference equation: Pref1 = P1 + P2 + 2*sqrt(P1*P2)cos(180) Pref1 = 111.1mW + 87.78mW + 2*sqrt(111.1*87.78)(-1) Pref1 = 198.88mW - 197.51mW = 1.37mW Thus after only one internal reflection cycle, the reflected power, Pref1, is reduced to 1.37mW, not to 23.32mW as you have asserted. If you will use a transmission line example and deal with voltages, you will be able to diagnose your mistake. Voltages interfere, watts don't. Most RF engineers simply do not understand how to deal with powers associated with component wave interference. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |

Pref1 = 198.88mW - 197.51mW = 1.37mW Hi Fred, You've missed the point entirely, the equation above already consigns 1.37mW to total darkness. Or any other non-zero result is reduced to zero for rhetoric's sake (I will skip the love fest of agreement that did not blossom). Odd how far this got with everyone presuming that these powers, energies, or candelas per square foot per fortnight were visible in the first place (perhaps to some breed of Ubermensch).

Good lord Richard, did you check the reference? It was a friggen joke!

No, it doesn't. 1.37mW is the total reflection AFTER ONLY ONE INTERNAL REFLECTION DURING THE TRANSIENT STATE. The rest of the reflection is canceled by the subsequent reflections. The steady-state equation is: Pref1 = P1 + P2 + 2*sqrt(P1*P2)cos(180) Pref1 = 111.1 + 111.1 - 2*sqrt(111.1*111.1) = ZERO P1 = Pfor1*rho^2 = 1000mW*0.1111 = 111.1mW P2 = Pref2*(1-rho^2) = 125*0.8889 = 111.1mW Reflections are completely canceled during steady-state!!! YOU missed the point entirely. I was merely pointing out the mistake you made when you got 23.32mW after the first reflection instead of the correct 1.37mW. The interference during the transient state is not total. The interference during steady-state is total. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

Suddenly, God realized that St. Peter was right and He was wrong. God's subsequent logic went something like this: I am God. I am omniscient. I am incapable of being wrong. Since I now know the correct answer, I must have known it all along. Since St. Peter was previously arguing with me, St. Peter must have been wrong all along. Now replace "God" in the above with "Jim Kelley" and you will get a picture of what has been happening with our postings. To the best of my knowledge, the only argument we have left is whether there is enough time for wave cancellation to actually take place. We agree on virtually everything else technical. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
