I am start working on metamaterial absorber as beginer. So firstly I'm trying to recreate some mode on COMSOL that already exist for learning purpuse. I failed to apply the TE and TM mode on selected port. I may have a little knowledge about it. How can I apply TE and TM mode on the model. Or how can I understand which polarization mode is working?!

In regard to modes, are you talking about a wave in a waveguide, cavity, and/or transmission line? If not, then "modes" are probably not of direct interest to you. You also mention polarization. A "mode" is a spatial distribution of fields, and is not the same thing as a "polarization," which is a local field characteristic. Now, if by some chance you are talking about reflection, scattering, or absorption at a material surface subject to illumination by a plane wave, then such plane waves can normally be decomposed, at the surface in question, into TE-type and TM-type incident waves. (see https://phys.libretexts.org/Bookshelves/Electricity_and_Magnetism/Book%3A_Electromagnetics_II_(Ellingson)/05%3A_Wave_Reflection_and_Transmission/5.05%3A_Decomposition_of_a_Wave_into_TE_and_TM_Components among others.) In that case, you most likely should apply Comsol's scattered wave formalism (and then you may or may not be interested in using any ports at all). Anyway, if you can tell us more about your problem, and/or post your .mph file, you will likely receive more specific and useful advice.
