Whereas, in Spherical coordinates IWavePhi & IWaveTheta decides the incident angle or direction of propagation, and values of Eo vector (phi & theta) determines the E vector components, thereby defines the resultant E. So 'the polarization is phi directed' means the E vector (resultant) has only Ephi component. ANSOFT HFSS FIELD CALCULATOR COOKBOOK ...

The other parameter of elliptical polarization - the axial ratio, can be determined as well from these plots. The ratio of the peak output (in this case 1.0 when the angle is 45 degrees) to the minimum power output (in this case 0.5, when the angle 8s 135 degrees) gives the axial ratio (1/0.5 = 2 = 3dB).

Cross-Polarization and Co-Polarization. As mentioned above, the different polarizations form many orthogonal pairs. Co-Polarization is defined as the polarization the antenna was meant to radiate, while Cross-Polarization is defined as its orthogonal pair. A purely polarized antenna will have low cross polarized radiation.

Thus linear and circular polarization are the two special cases of elliptical polarization. Linear polarization may be further classified as being vertical, horizontal, or slant. Figure 2 depicts plots of the E field vector while varying the relative amplitude and phase angle of its component parts. Figure 2.  

As, from HFSS you can easily check by plotting the behavior of electric field and magnetic field as well as you can also easily get the types of polarization for antenna you have designed. by seeing the nature of radiation pattern in 2 D (polar plot), you can decide the plane of polarization and types of polarization. Cross polarized wave (XPW) generation is a nonlinear optical process that can be classified in the group of frequency degenerate [four wave mixing] processes. It can take place only in media with anisotropy of third order nonlinearity. HFSS-IE also off ers a Physical Optics (PO) solver for solving electrically large problems where the currents are approximated in the illuminated regions and are zero in shadow regions.
