對多層涂型介質(zhì)的電磁波傳輸特性分析
摘要：變化著的`電場和磁場相互激發(fā)，形成空間中傳播的電磁波。本文根據(jù)電磁波的傳播特性，研究在涂型層狀介質(zhì)中傳播規(guī)律。同時從經(jīng)典麥克斯韋電磁場理論出發(fā)，推導出復相對介電系數(shù) 和復相對導磁率 的表達式；引入法向阻抗的概念，探討了涂型層狀介質(zhì)的反射和透射情況；利用計算機輔助設計，計算了在5-12GHz內(nèi)涂層介質(zhì)第1，第2級反射系數(shù)；提出尋找介質(zhì)層匹配的可行性方案；結(jié)合實際情況，討論兩種實例，并對結(jié)果進行了分析。

The Study The Electromagnetical Characterrlstics of Multilayer Medium
Abstract: With the motivation mutual of changing electric and magnetic fields, the electromagnetic wave which propagates in the space forms. Based on the Propagation Characteristics of electromagnetic wave, the propagation law is studied in the Precoat layered media in the article. Based on the classical electromagnetic theory of Maxwell, the expression of the relative dielectric constant and relative magnetic permeability is deduced also; Reflection and transmission of the Precoat layered media are discussed by introducing the concept of normal impedance; The first-level and second-lever reflection coefficient in the 5-12GHz Precoat layered media are calculated by the design of computer aided; The feasibility of the scheme; Here we will present the best program to realize the match of the different layers; According to actual condition, two examples are discussed, and the results are analyzed .
