矩形介质波导阵列的一种新型分析方法
A New Analytic Method for Rectangular Dielectric Waveguide Array
【摘要】 本文将等效介电常数近似分析方法在应用范围和处理方法上进行了一些改进.发展为双等效介电常数近似分析法,然后用它来分析矩形介质波导阵列.推得两个一维周期的耦合特征方程。如果将Macatili方法应用范围扩展用来研究该波导阵列也会得到同样的结果,它们都能在二维平面上较准确地反应出通带和阻带等主要周期特性。
【Abstract】 Abstract: In is paper the approximate analytical method of the effective dielectric constant is improved in thescope and operation, which is called the method of double effective dielectric constant. Based on it we analyzedrectangular dielectric waveguide array (RDWA) and obtained two coupled one-dimensional periodic characteristicequations. If the developed Macatili method is also used to treat the RDWA, the same result can be obtained. Twomethods can precisely show periodicities, for example, for pass band, stop hand and so on.
