| Abstract: | he field expressions are given by using electric Hertz potential in order to investigate the influences of axial conductor on the attenuation rates of electromagnetic waves along leaky coaxial feeder in the rectangular tunnel.The procedure described here can also be adopted to analyse the field structure and antenna excitation as well as for other tunnel model.The attenuation rates of modes in the single and double wires. |
