Abstract

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.

沿电磁晶体的主要光轴定向的EBG波导中的波

摘要

研究了具有方形光栅的电磁晶体中波导的本征波。晶体由放置在两个平行屏幕之间的金属圆柱组成。波导沿晶体的主要光轴定向。通过从晶体中分别去除一，二和三圆柱行来形成所研究的单行，两行和三行波导。在HFSS系统中以本征波模式进行电动力学建模。获得了特征波传播常数对频率和结构参数的依赖性。确定所有波导的最小和最大带宽频率以及带宽，并推荐其最佳参数。
