Acoaxial transmission line has inner and outer conductor radii a and b. between conductors (a < rho < b) lies a conductive medium whose conductivity is Ο (rho) = Ο 0/rho, where Ο 0 is a constant. the inner conductor is charged to potential v0, and the outer conductor is grounded. (a) assuming dc radial current i per unit length in z, determine the radial current density field j in a/m2. (b) determine the electric field intensity e in terms of i and other parameters, given or known. (c) by taking an appropriate line integral of e as found in part b, find an expression that relates v0 to i. (d ) find an expression for the conductance of the line per unit length, g.
