What is the principle of a Method of Moments analysis?
- A.A wire is modeled as a series of segments, each having a uniform value of current (correct answer)
- B.A wire is modeled as a single sine-wave current generator
- C.A wire is modeled as a single sine-wave voltage source
- D.A wire is modeled as a series of segments, each having a distinct value of voltage across it
WhyA Method of Moments analysis models a wire as a series of segments, each having a uniform value of current. A Method of Moments analysis works by modeling an antenna's wire as a series of small segments, each assigned a uniform value of current, then solving the resulting system of equations for those current values across every segment, answer A. It doesn't model a wire as a single sine-wave current generator or voltage source, and it doesn't assign a distinct voltage (rather than current) to each segment, those don't describe the actual segmented-current approach Method of Moments uses.
