有限要素法을 利用한 光채널 導波路의 모드 傳送에 關한 硏究 = A Study on Mode Propagation in Optical Channel Waveguide using Finite Element Method

다국어 초록 (Multilingual Abstract)

A vector variational formulation is essential when the scalar formulation is inadequate because of the presence of inhomogeneous or anisotropic materials.
The finite element method is used for all these problems, the entire cross-section of the region of physical interest is subdivided into a set of triangular subregions, called
The field functions are defined by a set of algebraicpolynomials over each elements.
An extrenum functional is then minimized with respect to the values of the field components at vertices of the elements.
In this way, the minimization generates a set of linear algebraic eigenvalue equations.
Subspace iteration, one of the most efficient methods, has been used to solve highly sparse matrix eigenvalue problems, talking full advantage of the sparsity.
In this paper, the mode propagation in channel waveguides is analyzed using finite element method.
