natural mode
Examples
- This paper lays emphasis on the problem of extracting the isolated eigenmode in spectrum and the iteration accelerating
本文重点研究eigenmode模块算法如何实现对频谱中孤立本征模的萃取及其中遇到的加速迭代的问题。 - In the course of filtration , interpolation is the essential step to produce the intrinsic mode functions , and the basis of the hilbert spectral analysis
在筛选过程中，插值是产生本征模函数关键的一步，是希尔伯特谱分析的基础。 - Therefore , research on improving the image resolution of sar and isar continuously has been a hot as well important topic . time series echo signal can be decomposed to imfs ( intrinsic mode function ) by emd ( empirical mode decomposition ) algorithm , which is distributed following frequency
经验模态分解( emd : empiricalmodedecomposition )方法能够把时间序列信号分解成有限数目的本征模态函数( imf : instrinsicmodefunction ) ,分解结果按频率高低分布。 - Operating modes of ln one - dimension anisotropic aeo device and kdp two - dimension isotropic and anisotropic aeo device are determined . the principle to determine electro - optic operating mode is that the difference of two intrinsic diffractive index doesn ’ t contain nature birefringence and the acousto - optic operating mode should achieve a higher acousto - optic merit value to improve the efficiency
选择电光工作模式时,以所选取的电光工作模式的两个本征模之差不含有自然双折射量为最佳模式;选择声光工作模式时,以声光优值尽可能大为原则,以便提高器件的衍射效率。 - First of all , the algorithm base on the boundary problem of helmholtz equation and finite - difference technique , calculate the field in “ cold ” cavity and disperse the helmholtz equation , as a result of the formula : ax = x . secondly , according to the eigenvalue of matrix theory and applied iterative methods , eigenmode adopt a numerical approach which allows the improved chebyshev polynomial iteration which based on the power method to extract the isolated eigenmode in the spectrum . finally , we resolve the problem of compatibility in software and insert the eigenmode module into the chipic which will have the function of eigenmode analysis
具体的说: ( 1 )首先以电磁理论中的亥姆霍兹方程的边值问题理论和计算电磁学中的有限差分法为基础,计算冷腔中的场分布并离散亥姆霍兹方程,得到标准的本征值问题: ax = x ; ( 2 )然后根据矩阵理论中的eigenvalue问题和数值计算中的迭代方法,采用改进后的chebyshev多项式,在power迭代法的基础上对ax = x进行多项式迭代,实现对频谱中孤立本征模的萃取; ( 3 )最后将用fortran语言编制的eigenmode模块加入到chipic软件中,解决了eigenmode模块与chipic主代码的兼容问题,从而实现了chipic软件的模式分析功能。
