Question

3). Consider a transmission line of length l made of conductor with resistance per unit length R, inductance per unit length L, between the two lines is dielectric material with conductance per unit length Gand capacitance per unit length C. (a) Check that the general solution of the transmission line equations is correct by substituting it back to the equations. (b) Given that the load has impedance ZL, and the generator has impedance Zg and voltage Vg(t), solve the voltage and current in the line at position d from the load at time t for a lossless line. (c) Suppose the impedance of the load can be tuned by you, under what condition can there be no reflected signal in the transmission line? (No matching network is needed in this case.) (d) Discuss under what condition can the coaxial transmission line be treated as two simple conducting line with no electromagnetic wave propagating inside.
