“The antenna, like the eye, is a transformation device converting electromagnetic photons into circuit currents; but, unlike the eye, the antenna can also convert energy from a circuit into photons radiated into space. In simplest terms an antenna converts photons to currents or vice versa.” Antennas, Second Edition, 1988, by John D. Kraus. Page 19. What about it? Is there some reason why RF photons should not exist? -- Rick |

Is there some reason why RF photons should not exist? There are a lot of people that believe that light is somehow special and the dual nature of all electromagnetic radiation doesn't exist. Most of them base this on the fact that it is impossible with current technology to detect a single photon at frequencies lower than light. -- Jim Pennino |

Radiating RF at the same wavelength as light will produce an electromagnetic field that is not visible to any eye. Babble; light IS electromagnetic radiation. https://en.wikipedia.org/wiki/Light If you think that photons will be converted to electric current on an antenna, try flashing a light on any antenna and check for results. Babble; antennas for light frequencies have been contructed in labs and guess what, they produce a voltage. Research continues to make them a practical solar energy converter. http://arxiv.org/pdf/1204.0330v1.pdf https://en.wikipedia.org/wiki/Nantenna http://www.nature.com/nphoton/journa....2010.237.html Please report back any findings here. :-) I find you are an ignorant babbler. -- Jim Pennino |

They do not produce light. http://arxiv.org/pdf/1204.0330v1.pdf https://en.wikipedia.org/wiki/Nantenna http://www.nature.com/nphoton/journa....2010.237.html Please report back any findings here. :-) I find you are an ignorant babbler. Yet still, you have not tried your flashlight on any type of antenna to produce a signal. Try harder. Again, for those who understand physics here, a very short wavelength electrical signal sent to an a tuned antenna at the frequency of say red light will produce zero light. It will produce electromagnetic radiation. They are not the same. If you are so sure, just prove us all wrong and win the Nobel Prize in physics. |

Obviously shining a light on an antenna designed for MHz frequencies will not produce an electric current, but shining a light on an antenna designed for THz frequencies will. http://arxiv.org/pdf/1204.0330v1.pdf https://en.wikipedia.org/wiki/Nantenna http://www.nature.com/nphoton/journa....2010.237.html Please report back any findings here. :-) I find you are an ignorant babbler.

It will produce electromagnetic radiation. They are not the same. Shining electromagnetic radiation on an antenna of the appropriate frequency does not produce electromagenetic radiation, it produces an electrical current, idiot. If you are so sure, just prove us all wrong and win the Nobel Prize in physics. I already gave you three links on the subject, idiot. -- Jim Pennino |

THz scanners are being used to detect weapons, etc. However, although they are even being used at some airports, there is much worry, as these frequencies are particularly useful to tear DNA/RNA apart. I don't think anyone has seen them emitting any light, but perhaps the THz freqs are simply shredding the light receptors in the victims/viewers eyes ... lol |

It will produce electromagnetic radiation. They are not the same. If you can prove they are different then you will be the one in line for a Noblel prize. If you are so sure, just prove us all wrong and win the Nobel Prize in physics. At least one Nobel prize has already been awarded for parts of that proof.
