Very nice analogy. BTW. VSWR is Voltage Standing Wave Ratio. When a transmission line is terminated with an impedance, that is not equal to the characteristic impedance of the transmission line, not all of the incident power is absorbed by the termination. Part of the power is reflected back so that phase addition and subtraction of the incident and reflected waves creates a voltage standing wave pattern on the transmission line. |
