A coaxial air transmission line has a solid conductor with a radius a on the inside and a very fine conductor with an inner radius on the outside. The conductors of this L-length coaxial transmission line include a lossy dielectric with electrical permeability E1, conductivity o1 and magnetic permeability u0 in the region a<r <c, and a lossy dielectric with electrical permeability E2, conductivity o2 and magnetic permeability u0 in the region of c <r <b. According to this,
a) Draw the geometry of the problem.
b) Find the resistance R, the capacitance C, the inductance L and the conductivity G per unit length of the air conduction line.
c) Find the current density of the face in each region.
d) Find the surface charge densities on the internal and external conductors and at the interface between the two lossy dielectrics.
