I am not sure what do you mean "connect". You can use script to modify their relative positions:


similarly for yz.

You can also add them into a structure group:


Symmetry can only be performed with boundary conditions. When the device AND the source polarization have symmetry, you can apply symmetry BCs. Using

?getnamed("FDTD","x min bc");  to get the current x min BC. you can set it:

setnamed("FDTD","x min bc","symmetric"); for symmetric BC

 setnamed("FDTD","x min bc","anti-symmetric"); for antisymmetric BC

Other direction is similar.

Please refer  Symmetric and anti-symmetric BCs in FDTD and MODE

Please try.
