The field distribution and the coupling loss of the leaky coaxial cable are studied by using the dyadic Green's function of second kind in the cylindrical coordinate.
The present method can be extended to the analysis of the dynamic behavior of liquid-structure coupling of cylindrical container in the case of three-dimensional liquid sloshing.
