| Jan 15, 2017 at 22:02 | comment | added | user130529 | @Kosha Misa : my conclusion (I will add it to the answer) is that your divergence free assumption does not hold. Note that this is not really surprising: you cannot expect the waveguide to transmit something without having charges moving around in the inner conductor (hence the non zero divergence there). | |

added another step to the conclusion
