over which direction the energy goes. The problem has always been with your overly imaginative explanation for how it gets there. I'm just quoting "Optics", by Hecht for how it gets there. Hecht's irradiance equation tells the whole story. Total Irradiance = I1 + I2 + 2*SQRT(I1*I2)cos(A) where A is the angle between the I1 and I2 electric fields. The last term is the interference term. If it is positive, the interference is constructive. If it is negative, the interference is destructive. If it is zero, the signals are orthogonal to each other and no exchange of energy takes place. Please note that the dimensions of Irradiance and the dimensions of average power flow vectors (Poynting vectors) are the same. Hecht says that in the localized absence of a source, any constructive interference must be equaled by the same magnitude of destructive interference. The destructive interference that eliminates reflections on the source side of the thin-film coating on non-reflective glass is exactly offset by an equal magnitude of constructive interference on the other side of that thin film surface. It's all there in "Optics" by Hecht. -- 73, Cecil, w5dxp.com |

No point in waiting two days for Cecil's fruitless search for Xeroxable material - even with a latitude of one order of magnitude slop above and beyond his usual ±69%. A Photon in the (bottom of the) 80M band would have the equivalent temperature of: 60µ°K for extra credit, the answer would have to have fallen somewhere in the range: 6µ°K..600µ°K Still pretty darn cold (and a far sight harder to answer than simply stating near 0°K which was a sufficient answer in the first round). This, of course, is simple Black Body radiator mechanics that novices in Optics would have migrated through in High School. Cecil's Photon radiator seems to need serious back-flushing. Dare I challenge our master of Xeroxphotonimetry as to the temperature of a 10M Photon? It would seem that if you cannot compute the simple matters of heat, you are certainly the person who needs to ask "Where Does the Power Go?" :-0 Awaiting more Photonic (no, I did NOT misspell pathetic) nonsense from Cecil.... 73's Richard Clark, KB7QHC |

BE&E, AVA, AFTA, and C7 1980 for the first term schools, and 88 for C7 Hi Dana, Welcome to the group. To explain the alpha-numeric soup in my reply, I was trained in Radar Systems before being cross-trained as an instructor in RF Communication Systems (I then migrated into Precision RF power measurement out to 12GHz). The first class I taught was a two week course in the theory and maintenance for the Collins R-390. I also taught the four week course for the Collins URC-32 (very few seen in amateur application as KWT-6). I taught other equipment as well, but they are even more obscure to Hams. The Collins gear was like learning to drive and maintain a Rolls-Royce. 73's Richard Clark, KB7QHC |

It would seem that if you cannot compute the simple matters of heat, you are certainly the person who needs to ask "Where Does the Power Go?" :-0 Hi All, Pushing further down the humiliation trail, if one considers the pain of lowering temperatures into the microKelvins, one question arises: How? Dare I day photons? ;-) Those same photons to have been claimed to be the source of ALL fields and the inspiration for electrons are used to "calm" atoms (or corral them) so that their jitters are reduced along with temperature. Hence we return to Cecil's inability to express photonic pressure where it counts most (shuffling those atoms). At the jeopardy of starting more gibbering, we have photonic tweezers that move atoms around in quantum dots. The next esoteric observation comes with the introduction of the Phonon, which is a sound wave that can move through material faster than light. That, of course, is highly qualified because phonons migrate through far more materials than light can. Albeit that rare distinction, the frequency of that sound commonly pushes past 10s of Terahertz (or as low as an 80M QSO). The Phonon (not the Photon) would be that natural progression into "Where Does the Power Go?" but would be another fumble at the 1 inch line with a goal-to-goal reversal. 73's Richard Clark, KB7QHC |

The Collins gear was like learning to drive and maintain a Rolls-Royce. I was an I level DECM tech. I maintained the ALQ126, countermeasure system, the ALR 45, 50, and 67, receivers and pulse analyzer, the USM 406, flight line test set, the box that helped the O level guys sweep the lines and verify the ew equipment, and the ALM 106 test bench, one of the first automatic test benches made, and its replacement the USM 458. I was assigned to an A6 squadron, that swapped out a few years before I got out to FA18's, but I was detailed out to support them via the IMA shop. I went into comm, when I got out, worked for a Motorola service shop maintaing smartnet trunking systems, as well as conventional repeaters and systems, then went over to Nextel as a cell site tech/performance engineer, and then over to VoiceStream as a switch tech and performance engineer. I see that guy has not answered yet about the temp, that thread is kind opf amusing. 73's Richard Clark, KB7QHC |
