Imaginary component of E field?

      HFSS gives the E field over a structure as a complex number at a given phase and frequency. Since you can choose the phase and frequency of the field you want to view, what does the imaginary component of E represent? Is it a global phase? Or is it the complex conjugate part of the field expression as in the below picture?

      both your statements are right. at certain moment of visualization time the phase is global for all the postprocessed data.nthe data that was solved in frequency domain has to time-variant exponent, thus the relative changes in the field phase along the structure reflect the wave phase delay. It should be given in high school, or on the first course, depending on countryn

      nThank you for reaching to us and we appreciate your patience.nThe imaginary component of electric fields represents the global phase.nAll the very best.n
