적응요소 MLFMA를 이용한 유전체가 포함된 3차원 구조의 정전용량계산
A fast capacitance extraction algorithm for multiple 3-dimensional conductors with dielectrics using adaptive triangular mesh
초록
This paper describes to extend the MLFMA(Multi-Level Fast Multipole Algorithm) for three-dimensional capacitance computation in the case of conductors embedded in an arbitrary dielectric medium. The triangular meshes are used and refined in the area which has heavy charge density. This technique is applied to the capacitance extraction of three-dimensional structures with multiple dielectrics. The results show good convergence with the comparable accuracy, and this adaptive technique coupled with MLFMA is useful to reduce computing time and the number of elements without additional computational efforts in large three dimensional problems.
