Coaxial cable

How does signal propagate in a coax cable. Is it in the form of EM waves or in the form voltage/current?

Re: Coaxial cable

The EM wave is actually generated due to the voltage and current applied to the transmission line (coaxial cable in this case).

So when you apply a voltage to the TL the current passes through it and an EM wave is generated.

I hope this was helpful
 

Re: Coaxial cable

The mode is TEM (transverse electric and magnetic) The propagation is in the space between the conductors. The RG in the US military cable designators stands for radio guide.
