Abstract :
Using an idealized theoretical model, the inadvertent mode conversion between the bifilar and monofilar modes are dealt with in a tunnel that contains a braided coaxial cable. The tunnel is allowed to have various kinds of lateral nonuniformities such as changes of wall conductivity and permittivity. We conclude that such effects are very important in understanding leaky feeder systems.
