摘要
本文在用色散图法分析了目前主要存在的两种能够传输准TEM波的缝隙波导的特性基础上,设计了一种能够传输准TEM波的新型平行板缝隙波导,通过对色散图的仿真研究其缝隙高度对波导传输特性的影响以及通带范围内波的模式特性,该缝隙波导具有相对较大缝隙尺寸,使其能够方便地应用于测量具有周期结构的人工电磁材料电磁参数。
This paper discusses the two types of new gap waveguide which can support quasi-TEM waves and designs a new parallel plate gap waveguide supporting quasi-TEM waves. Through simulating the dispersion diagram to analyse the influences of the gap height on the characteristic of gap waveguide and the modes of waves in bandwidth. The designed new parallel plate gap waveguide has a relatively larger gap which is convenient to be used in measuring electromagnetic parameters of artificial electromagnetic materials.
