Polarization Ratio

The IEEE defines the (complex) polarization ratio as, "For a given field vector at a point in space, the (magnitude of the) ratio of the complex amplitudes of two specified orthogonally polarized field vectors into which the given field vector has been resolved." [Ref. 2] HFSS computes the following six polarization ratios at each selected aspect angle:

(1)

(2)

(3)

(4)

(5)

(6)
