Development of a methodology for transitioning from a spectral equation relative to a spatial variable to a differential equation relative to a spectral parameter in the Sturm-Liouville problem for a one-dimensional periodic two-layer photonic crystal

open access: yesВісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка
Relevance. In connection with solving the problem of scattering of electromagnetic waves (diffraction problem) on objects such as photonic crystals (one-dimensional periodic unbounded), it is important to study the dispersion relation.

在有限區間向量型Sturm-Liouville方程式的唯一性定理

open access: yes, 2013
博士關於定義在區間的非對稱形Sturm-Liouville 微分方程式的反問題研究及學習,Yurko ( [24] , 2006)利用Weyl矩陣,提出了矩陣邊界值問題的反問題有唯一性的定理。 在本篇論文,首先;對於Sturm-Liouville矩陣微分方程式含有一般的邊界條件的反問題,我們將証明ㄧ般的h1 , H1,亦可得到Q(x)有唯一性。利用矩陣型式邊界值反問題的唯一性,我們主要工作是在向量微分方程式邊界值反問題上,探求向量頻譜(spectral sets)與位階函數Q(x)唯一性的關係 ...
