8.(14 points) An infinitely long lossless coaxial transmission line has inner conductor radius a, outer conductor radius b, and is filled with a material with permittivity e = ere and permeability u = 40. Ignore the outer conductor thickness. (a) (3 points) Assume some charge per unit length + L on the inner conductor and -PL on the outer conductor. Find the electric flux density between the conductors. (b) (3 points) From part (a), find the voltage between the conductors. (c) (1 point) Find the capacitance per unit length. Yes, this expression is given in the textbook. Use that result to check your answers for the previous two parts. (d) (3 points) Assume that the inner conductor carries z-directed current I, and the outer conductor carries current -1. Find the magnetic field intensity between the conductors. (e) (3 points) Find the magnetic flux per unit length linking the current on the conductors. (f) (1 point) Find the inductance per unit length. Yes, this expression is given in the textbook. Use that result to check your answers for the previous two parts.
