Frankly, I thought the guy would have shown up by now laughing. *Having had a great laugh on us for attempting to take him seriously ... has me wonderin'! 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 |
