Abstract—EBG waveguides in an electromagnetic crystal are studied in the form of a two-dimensionally periodic array of metal cylinders located between conducting screens. The dispersion characteristics of waveguides formed by removing one, two, and three rows of cylinders along the diagonal of a square crystal lattice are obtained. As a result of analyzing the frequency dispersion of the fundamental waveguide modes and eigenmodes of a homogeneous crystal, the factors limiting the operating frequency bands of the waveguides are determined and the lattice parameters optimal from the aspect of the band properties are obtained. The characteristics of waveguides oriented along the diagonal of the crystal lattice are compared with similar characteristics of waveguides formed along the principal axes in crystals with a square lattice.

摘要电磁晶体中的-EBG波导以位于导电屏之间的金属圆柱的二维周期性阵列形式进行研究。获得了通过沿着方形晶格的对角线去除一排，两排和三排圆柱而形成的波导的色散特性。分析了均质晶体的基本波导模式和本征模式的频率色散的结果，确定了限制波导工作频带的因素，并获得了从频带特性的角度出发最佳的晶格参数。将沿着晶格的对角线定向的波导的特性与在具有正方形晶格的晶体中沿主轴形成的波导的相似特性进行比较。
