Dear coilers,
I have just sent out some info to the list regarding the 1/4 lamda
theory about one hour ago. But I have not seen my postings yet. I
will resent it if it does not appear in the next two days, as long
as it is still useful for us and you have no objection.
Basically I am trying to give the info on stationary wave, where 1/4
lamda can be tuned to attain resonant for a wave of wavelength
shorter than the physical size of the transmission line, which can be
in any media.
The electrical length is given by c/(2*pi*f), where c is the speed of
light in free space and f is the frequency under consideration. The media
is characterized by its characteristic impedance together with its TE0x
mode.
This application is very common in microwave network and long distance
power transmission; in both cases, the electrical length of the wave is
shorter than the physical size of the network. However, it is not that
useful in low frequency light electronic application.
I am not a coiler, but I read some tesla's articles, where he kept
mentioning the stationary wave in hf electricity. bye-bye!
