Note that there is a second valid solution. Problem #2) When an air-filled, slotted-line is terminated with a "short-circuit", voltage minima are measured at positions of 10cm and 25cm on the line. When an unknown load" is connected to the line, the VSWR on the line is 2.4, and voltage minima are detected at 16cm and 31cm. Determine the impedance value of the load in rectangular form), the reflection coefficient of the load (in polar form), and the frequency of...
