The papers are these two: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=829803" http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=829801" I have done some further reading but I'm still far from completely understanding. My rough conclusions are that it has to do with the...

Strange, it's not dead for me. Anyway, yes they do. Like I said above, the cables have periodic slots from where radiation leaks out. And this is true for the whole length of the cable. The whole cable "radiates". You do have to be careful, though, not to let the full radiation leak out before...

I agree with (i) because electric field lines always point from positive to negative charge. This is what a battery does. Creates a potential difference. What I don't understand is why do you believe there is an EM wave in DC current? If you talk about the light switch in your home, then yes...

Here is the link for anyone that is interested: http://urgentcomm.com/mag/radio_leaky_cables_good/" The article also says that coupled mode cables resemble surface wave antennas. In these antennas the signal is traveling as opposed to the resonant antennas where it is a standing wave. When...

I am trying to understand how leaky cables work, and especially those that permit higher frequencies (I think about 2.4GHz), but I am quite new to electromagnetics in general. For clarification, leaky cables are usually coaxial cables that have apertures in their outer conductor from where an...
