Abstract
Modified two dimensional photonic crystal waveguide with different values of vacuum holes radius in two rows on the hollow channel edges is considered. Dispersion properties of surface even and odd modes in photonic crystal waveguide are studied. Spatial distribution of the longitudinal component of electric field changes for different configurations of the modified photonic crystal waveguide. Increase of the vacuum cylinder normalized radius in two rows on the waveguide channel edges results in increase and decrease of the electromagnetic field intensity of the even and odd surface modes in the central part of hollow channel respectively. Therefore, application of the modified waveguides in electron devices can be perspective for efficiency enhancement of beam-wave interaction.
