Propagation Characteristics Analysis of Dielectric Waveguide Using a Finite-Element Method
유한요소법에 의한 유전체 광도파관의 전파특성 해석
Abstract
The most serious difficulty in using the finite element method is the appearance of the so-called spurious, nonphysical modes. We have proposed the finite element formulation of the variational expression in the three-component magnetic field based on Galerkin's method. In this approach, the divergence relation H is satisfied and spurious modes does not appear and finite-element solutions agree with the exact solutions.
