    為了使本論文的研究成果便于應(yīng)用于共面波導(dǎo)的計(jì)算機(jī)優(yōu)化設(shè)計(jì)中,最好方法是得到封閉的解析表達(dá)式,所以本論文采用了保角變換理論宋分析非對(duì)稱共面波導(dǎo),并且應(yīng)用了優(yōu)化計(jì)算方法、保角變換反演技術(shù)和數(shù)值預(yù)測(cè)糾正算法對(duì)各種非對(duì)稱共面波導(dǎo)的特性以及場(chǎng)結(jié)構(gòu)進(jìn)行求解。
  • This thesis is to recommend a important class of regularized strategies for solving inverse problems - mollifier method . it anaysises the consistency , numerical stability and error estimates of mollified solution . similar to tikhonov regularization , a discrepancy principle for selecting the mol - lifier parameter is proven and applications to numerical differentiation and numerical inversion of abel transform and also given
    本文將介紹求解反問(wèn)題的一類重要的正則化策略?緩鎮(zhèn)法,并基于用gauss核構(gòu)造的緩鎮(zhèn)算子,分析了緩鎮(zhèn)解的相容性、數(shù)值穩(wěn)定性和誤差估計(jì),與tikhonov正則化類似,我們證明了決定緩鎮(zhèn)參數(shù)的偏差原理。
  • The prevailing approaches depend on costly time domain convolution , using the frequency domain network parameters such as s - parameter , y - parameter or abcd parameters to find analytic solution , and finding the time domain approximations by fft or even numerical inversion of laplace transform ( nitl ) if there are a large number of nonlinear devices in the network
    目前盛行的方法是采用費(fèi)時(shí)的時(shí)域卷積法:首先運(yùn)用諸如s 、 y 、 abcd的頻域網(wǎng)絡(luò)參數(shù)求出頻域解析解,然后通過(guò)快速福利葉變換( fft )得出時(shí)域近似解,如果網(wǎng)絡(luò)中存在大規(guī)模的非線性設(shè)備,還需要采用數(shù)值逆拉普拉斯變換( nilt ) 。
