Two Half GILD Electromagnetic Modeling in Micro Materials

摘要

In this paper, we present a two half dimensional electromagnetic (EM) modeling using the Global Integral and Local Differential (GILD) method. We derived the three dimensional and two half dimensional (2.5D) boundary integral-differential equation for the magnetic field. We construct 2.5D GILD EM scheme and developed 2.5D GILD EM modeling programs. The collocation finite element method (FEM) was used to discretize the new EM boundary integral-differential equation, and the Galerkin FEM to discretize the internal domain EM differential equation. The boundary FEM equations and the domain FEM equations are coupled into the completed GILD equation system. A new parallel decomposition from the internal domain to the boundary can be used to solve the 2.5D EM equation. The simulation tests in the micro materials show that the 2.5D GILD EM modeling is fast and accurate. The parallel 2.5D GILD EM code is high performance. An interesting GILD phenomena in the micro scale materials is presented that is breakthrough discovering.
