Consider a coaxial cable of inner radius a and outer radius b, filled with a lossless dielectric material. The phasor-domain fields inside of the cable (a < rho < b) for a time-harmonic wave traveling down the cable are given in cylindrical coordinates as:
E= rho (1/ rho)e^- jkz
H= φ (1/rho) 1/ ηo√εr. e^-jkz
Calculate the total time-average power (in Watts) flowing in the z direction down the cable.

Modern high speed trains do not have perpendicular expansion gaps where rails are joined end-to-end any more they are mostly welded together but what might happen if there was a spell of particularly hot weather that causes inspection of the tracks?
