The eigenwaves of waveguides in electromagnetic crystals with a square grating are studied. A crystal consists of metal cylinders placed between two parallel screens. The waveguides are oriented along the principal optical axes of the crystal. The investigated single-, two-, and three-row waveguides are formed by removing one-, two-, and three-cylinder rows from a crystal, respectively. The electrodynamic modeling in the HFSS system in the eigenwave mode is performed. The dependences of eigenwave propagation constants on the frequency and structural parameters are obtained. The minimum and maximum bandwidth frequencies and the bandwidths for all the waveguides are determined and their optimal parameters are recommended.
