Hi Steven, I'm trying to simulate an asymmetric PC slab. I'm using the display-zparities function in order to distinguish quasi-even and quasi-odd modes, but I also need to discriminate between TE and TM modes, because my slab waveguide doesn't support TM modes... To this goal, I'm using the output-dpwr function, I'm extracting the d-energy-components line through grepping, then if the in-plane component is larger than the out-of-plane one I consider that as a TE mode, and viceversa for the TM modes. Is it correct? I chose to use this procedure because in the paper "Guided modes in PC slabs" you write that higher-order modes can form nodes in the vertical direction, and you can have, for example, odd TE-like modes.
