Voltage standing-wave ratio in terms of reflection-coefficient magnitude is?

  • A(1+|Gamma|)/(1-|Gamma|)
  • B(1-|Gamma|)/(1+|Gamma|)
  • C1-|Gamma|²
  • D|Gamma|/(1+|Gamma|)
Report an error
Correct Answer: A. (1+|Gamma|)/(1-|Gamma|)
Explanation: VSWR is the ratio of maximum to minimum field amplitude and equals (1+|Γ|)/(1-|Γ|).
