Electromagnetism: A transmission line has a characteristic impedance Z0 = 50 Ω and attenuation 3 dB/100m (α = 0.345 Np/100m). Assume that the velocity factor is 1.0 (i.e. the propagation speed along the line is equal to the speed of light). The line is 500 m long and a load resistance, RL = 50 Ω is connected to one end of the line. A sinusoidal voltage source is connected to the line at the other end, with a peak voltage...

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 0.064uH, and when the line was open-circuited, the measurement yielded an input impedance equivalent to a capacitor with capacitance of 40uH. Find Zo of the line, the phase velocity, and the relative permittivity of the insulating material.
