摘要
不同介质层的组合,有别于单层介质,具有特殊的电磁特征,本文从经典的麦克斯韦电磁场理论出发,推导出相对复介电系数和相对复导磁率的表达式,引入法向阻抗的概念,在频段5-12GHz内,利用计算机对n层介质材料进行研究,提出寻找介质层匹配的最佳方案,结合实际情况,讨论了两种特例,并对结果作出分析。图5,表2,参5。
The medium with different constition layes is different from the single one. the former has a special electromagnetical characteristics. In this paper, We derive some formulas of relative complex permitimity ε_1~* and complex magnetic permeability μ_1~* from the Maxwells electromagnetical field theory. We introduce the concept of normal impedence. using a computer we studied the medium material within layers in the frequency range from 5 to 12GHz.Here we will present the best program to realize the match of the diferent layers, discuss two special examples and analyse the given results comparison with practice. 5figs., 2tabs., 5refs.
