In the study of directional spectrum and reflection coefficient of multidirectional wave , firstly the wave elevation trains overlapped by the incident wave and the reflected wave of multidirectional wave are simulated in the method of a frequency corresponding to a direction . then the composed wave trains are analyzed respectively by the mbdm and the mmlm . during the numerical study , the input factors include the various wave parameters , the different measuring wave system and the various reflect characteristic 在多向不规则波入射波方向谱和反射系数的分析研究中,利用方向频率对应法模拟了多向不规则波入射波与反射波叠加的波面序列,将此合成波列分别应用mbdm和mmlm进行分析,通过输入各种波浪参量、不同波浪测量系统和各种反射特性等因子,检验了mbdm和mmlm方法的适用条件,对两种分析方法的性能进行了比较分析。
But how to predict its reflected characteristics and equivalent electric and magnetic ( em ) parameters from components of the mixed material containing iron fibers , and how to make sure absorbing material ' s components from the required reflected characteristics , still has n ' t a viable method and calculating program . the purpose of this paper includes three contents . one is to research a method that we can calculate the oriented iron fiber mixture ' s em parameters from it ' s components 但是对于如何从涂料的配方预测其反射特性和等效电磁参数、并根据对反射特性的要求制定铁纤维吸波涂料配方还没有一套可行的方法和计算程序,本论文的目的是研究出一套根据涂料的配方求解定向铁纤维混合物的等效电磁参数的方法,提供实用的计算机程序,并对混合物的等效电磁参数与铁纤维的形貌、含量的关系进行分析,得出一些规律性的结论。
