A sinusoidal voltage wave of real amplitude B0, and frequency w, and phase constant B, propogate in the forward z direction toward the shorted load end in a lossless transmission line of characteristic impedance Z0. At the end, the wave totally reflects with a pi phase shift, and the reflected wave now interferes with the incident wave to yield a standing wave pattern over the line length.
a) Determine the standing wave pattern for the voltage in the line. Express the result in real insantaneous form and simplify
b) Determine the standing wave pattern for the current in the line,. Express the result in real instantaneous form and simplify
