Vector operation field

      Hello,

      Could anyone kindly tell me what each choices of the DFT monitor's vector operation field measure? There are magnitude, X, Y, and Z. Does the magnitude graph show the crest and troughs of an E field?

      Thanks

      Also, should the E field profile have negative values when I choose X as the vector operation field?

      First, field value is complex with real and imaginary parts, which can be positive and negative. For example, E=Er+i*Ei where Er and Ei can be positive or negative.

      xyz means Ex,Ey and Ez, magnitute is abs(E)=sqrt(abs(Ex)^2+abs(Ey)^2+abs(Ez)^2).

      Only real and imaginery shows phase,not the magnitude or absolute values.
