A 50 Ω lossless line is terminated in a load impedance zL = (30 – j20) Ω

Figure P2.34: Circuit for Problem

(a) Calculate Γ and S.

(b) It has been proposed that by placing an appropriately selected resistor across the line at a distance dmax from the load [as shown in Fig. P, where dmax is the distance from the load of a voltage maximum, then it is possible to render Zi = Z0, thereby eliminating reflection back to the end. Show that the proposed approach is valid and find the value of the shunt resistance.
