floquet port simulation using incident wave

    • hongseok choi

      To whom it may concern,

      My ultimate goal is to conduct a Semi-periodic simulation using 3D components. In this process, I have encountered two issues.

      First, my approach involves using a lattice pair and radiation boundaries to excite the incident wave from the input plane and extract 3D components for finite array simulation.

      When conducting a simulation using Floquet ports, the reflection magnitude and phase of S11 are correctly plotted. However, when I use the incident wave for simulation, the reflection magnitude is well plotted, but the phase remains consistently at 0 degrees. How can I ensure that both sets of results are consistent?

      Second, I've created a unit cell using the incident wave and exported it as a 3D component. I then imported this component into a hybrid simulation to create a 4x4 array. The simulation was completed successfully, but I couldn't extract S-parameters. How can I extract S-parameters in this scenario?

      Thank you very much for your time.
