摘要

本文提出了一种基于周期性加载金属脊的电磁带隙波导的被动结构快速、准确的全波分析工具。为此，采用一种非常有效的积分方程(IE)技术来模拟涉及任意波导的平面阶跃。采用边界积分-共振模态展开(BI-RME)方法得到脊波导的模态图。为了展示该工具的优势，分析了具有改进阻带性能的周期性加载e平面滤波器，并与标准实现进行了比较。推导了色散关系，并将其作为设计EBG五阶低通滤波器的准则。

Full-Wave Analysis and Applications of EBG Waveguides Periodically Loaded with Metal Ridges

In this paper, a fast and accurate full-wave analysis tool of passive structures based on Electromagnetic-Bandgap (EBG) waveguides periodically loaded with metal ridges is proposed. For this purpose, a very efficient Integral Equation (IE) technique is followed to model the planar steps involving arbitrary waveguides. The well-known Boundary Integral - Resonant Mode Expansion (BI-RME) method is used to obtain the modal chart of the ridged waveguides. In order to show the advantages of this tool, a periodically loaded E-plane filter with improved stopband performance is analyzed and compared to standard implementation. Dispersion relations are also derived and used as guidelines for designing an EBG fifth-order low-pass filter.
