A coax cable with 75 ohm characteristic impedance and operating at a frequency of 1.1 GHz is terminated by a load-impedance. The load impedance consists of a 180 ohm resistance. Explain what VSWR is. Calculate the voltage reflection coefficient and the VSWR.
A glass is half-full of water, with a layer of oil(n = 1.51) floating on top. A ray of light travelingdownward through the oil is incident on the water at an angle of72.9°. Take the refraction index of water to be1.333. (a) Determine the critical ang..
