A 60-(MHz) electromagnetic wave exists in an air-dielectric coaxial cable having an inner conductor with radius a and an outer conductor with inner radius b. Assuming perfect conductors, and the phasor form of the electric field intensity to be

a) find k,
b) find H from the × E equation, and
c) find the surface current densities on the inner and outer conductors.
