The input impedance of a 31-cm-long lossless transmission line

The input impedance of a 31-cm-long lossless transmission line

The input impedance of a 31-cm-long lossless transmission line of unknown characteristic impedance was measured at 1 MHz. With the line terminated in a short circuit, the measurement yielded an input impedance equivalent to an inductor with inductance of 0.064 ÂľH, and when the line was open circuited, the measurement yielded an input impedance equivalent to a capacitor with capacitance of 40 pF. Find Z0 of the line, the phase velocity, and the relative permittivity of the insulating material.
