This module automatically generates variables for the Jones vector elements. As for Polarization Plots, the variables are created for
Periodic ports in 3D and in 2D, if the
Electric field components for setting in the
Components section for the physics interface is set to
Three-component vector.
The variables are available for post-processing as global variables, with names based on what port boundary the variable is applicable for, the polarization direction, and the mode number. The context above is encoded in a variable name of the form
tag.JXYYY_Z, where
Thus, the variable ewfd.JROOP_0_n1 represents the Jones vector element for the out-of-plane mode in 3D with mode numbers
m = 0 and
n = -1 for a port located on the same boundary as the exciting Periodic port.
There are also variables for the norm of the Jones vector, named as tag.normJX_Z, where
X and
Z represents the boundary location and mode number, respectively. Thus, the variable
ewfd.normJR_0_n1 represents the Jones vector norm in 3D with mode numbers
m = 0 and
n = -1 for a port located on the same boundary as the exciting Periodic port.
The base vectors are available for evaluation on the port boundaries, with variable names like tag.eJXYYY[xyz]_Z, where
tag,
X,
YYY, and
Z have the same meanings as for the variables discussed above and
[xyz] is one of the Cartesian components. Thus,
ewfd.eJTIPx_p1, is the
x-component of the in-plane base vector for a 2D port, with mode number
m = +1, that is not located on the same boundary as the exciting port.
