Zak phase/ Berry Connection Photonic Crystals

Please login with a confirmed email address before reporting spam

Hi, I'm using COMSOL to solve eigenfrequency of photonic crystals. I obtained eigenfrequency, eigenmodes. How can I export all the eigenfunctions to calculate Zak phase? Can anyone help? Thank you in advance!
