Abstract

In this paper, we study EBG-waveguides in an electromagnetic crystal in the form of a two-dimensionally periodic lattice of metal cylinders with a triangular grid. The dispersion characteristics of waveguides formed by removing one, two, and three rows of cylinders along the orthogonal axes of the crystal are obtained. A parametric analysis of the critical frequencies of the waveguide modes and eigenwaves of a homogeneous crystal is performed. Electrodynamic modeling was performed in the ANSYS HFSS system using the eigenwave mode. The optimal parameters of the electromagnetic crystal, which provide the maximal operating frequency bands of waveguides with various orientations in the grid, are obtained. The characteristics of waveguides in crystals with triangular and square grids are compared.

具有三角形网格的电磁晶体中的波导结构

摘要

在本文中，我们研究电磁晶体中具有三角形网格的金属圆柱的二维周期性晶格形式的EBG波导。获得了通过沿着晶体的正交轴去除一排，两排和三排圆柱体而形成的波导的色散特性。对均匀晶体的波导模式和本征波的临界频率进行参数分析。使用本征波模式在ANSYS HFSS系统中进行电动力学建模。获得电磁晶体的最优参数，该最优参数提供了网格中各种方向的波导的最大工作频带。比较了具有三角形和正方形网格的晶体中的波导特性。
