Hi Nathan,

You can use FDTD to calculate different results such as the transmission, losses etc and how they change with different physical parameters of the structure. If the structure is mostly planar, and there is minimal vertical coupling of modes then you can use varFDTD, which reduces a 3D simulation to effectively a 2D one, thereby also reducing the memory/time requirements. If you want to perform circuit level simulation, then you can use INTERCONNECT.
