Regards, JS Hello all OK, this probabily is near a joke or hoax, but what about liquid/ionic/ dielectric in general? I have a pair of interesting links about it = http://ieeexplore.ieee.org/xpl/freea...number=1461138 http://xa.yimg.com/kq/groups/1508589...ennas_IEEE.pdf Time ago I had some doubts about the mobility of ions in a liquid to radiate and calculate how much an electron actually moves when the antenna is radiating to use as a starting point. The numbers (if I do not make mistakes) showed me to a current density in the order of 5 A/mm^2, free electrons can take a trip of just one three thousandth mm of copper ion radius, surprising result!, really I did not expect such a small value ..., It showed me that electrons in antenna barely vibrate around their resting place when radiates (I made calculations for a irradiant at 80 m). This favored hypothesis of liquid antenna possibilities because would suffice for the ions (charges) of the liquid vibrate slightly around their points of rest to act as radiators (I do not to solve issues related + ion mass to best "close" my questions). We know sea water an earth EM wave reflections really are reirradiation of EM energy, then, ionic antennas there are real things, are there? However I haven not study the efficience of this process. What do you think about it? Best regards Miguel LU6ETJ |

Two antennas were constructed, 25 mm and 50 mm in diameter, with salt solution at 35 ppt and 70 ppt.

Consider a dielectric lens antenna. How much mobility there? We know sea water an earth EM wave reflections really are reirradiation of EM energy, This reflection is a function of a severe mismatch between two poor conductors. You don't need sea water to achieve the same thing. What do you think about it? Consult the authority on invention: http://www.rubegoldberg.com/ 73's Richard Clark, KB7QHC |

I hope very well with yours: Mylar conductive ballon replacement it is not a valid refutation for the hipotesis analized, that antenna was only a "test antenna", any liquid antenna can be replaced by a metalic antenna...! what prove that? I was not be here fifty year ago :) (I suppose "ether" also must have been treated in this newsgropup a hundred years ago :D ) what you think about it (trees) at that time? I do not know lens dielectric antennas, I learnt radiation it due accelerating charges, electrons are charges, free ions also, non free dielectric charges (E field induced dipoles) too; alternating electric field applied to them produce movement on them, then acceleration, then = radiation. Am I wrong? (yes I know, loss too sometimes). You say: "This reflection is a function of a severe mismatch between two poor conductors. You don't need sea water to achieve the same thing" What "two" conductors? you know air not work as a "conductor" in this analitic environment, it would the same it there were empty vacuum, reflecting medium properties are responsibles for earth reflections. "Mismatch" it is another magic word, improper of you indeed my friend!, not an explanation :) Classic EM radiation (or the same "re-irradiation") it sometimes explained due accelarating charges, and YES, I agree with you, certainly "you do not need sea water to achieve the same thing", you can do it with any other vibrating charge, sea water charges it is only one possibility, conductors, soil substances are other familiar things capable to do it. We know waves are reflected to ionosphere by those mediums, we can explain that reflections with incident electromagnetic fields and earth surface induced currents; however, "current" not implies here free electrons traveling miles inside a conductor, we have a "current" with any little induced movement on a charge and if this movemente is not constant we have acceleration then = EM radiation, what other classical process could explain the EM earth reflection? I do not know. However I am not supporting practical liquid antennas here, I have not made the experience and I have not theoretical enough knowledge neither to prove or refute the hipotesis without much more working, I only have some pointers to think over about it. 73 Miguel LU6ETJ |

(Sorry, I don know how properly quoting with Google, let me use for your sentences). ......... Is not that IEEE paper what you called "the Workbench", have done your duties in "The Bench" to refute that paper? :D ...... What does it prove? What does water prove? That it is a poor replacement? Yes Certainly "a wooden leg it is a poor replacement for the original one" (Capt. Hooke dixit), but it is better than no leg at all when you do not have money to pay "the million dollar man leg". Science deals with possibilities not with Harvard economists efficientist laws. We, carbonous beings have made of electrolites, open your ham mind, what was about spirit of "to boldly go where no man has gone before"? ........ That repeated epithet is rather too simple. An electron is always accelerating. A circular orbit guarantees that. Time ago you have troubles with this item, until today do you not believes Bohr postulates was intended for atomic orbitals?, do you have forgotten ciclotron radiation?, I talked to you about this curious habit of emmiting waves of circular accelerated charges when we are young. ........ Does swinging a battery around produce radiation? Do you believe? ....... Air a POOR conductor of EM? Oh no! you are not my Clarke, this newsgroup has been infiltered by etherians. They have hi jacked my old newsgroup friend...! (electronic ether, where I read that, before?) ...... PSE explain me MISMATCH. (I bet that "mismatch" in some point will ends up in Maxwell's Faraday and generalized Ampere law). 73 (so much english for a day to me) Miguel Ghezzi |
