Abstract

HFCS, a 3D ElectroMagnetic (EM) simulator, is developed based on the Finite Integration Technology (FIT) so that Maxwell equations in any arbitrary geometry with known boundary conditions and free sources can be solved. As a first step, the FDTD-type grid is adopted. Thereafter, the Maxwell equations in integral form are discretized into the Maxwell Grid Equations through FIT and the eigenmode equation is obtained. Assigning material properties and boundary conditions, the eigenmode problem for a 3D geometry is established and then solved.

基于有限积分技术的特征值求解器
HFCS是一种基于有限积分技术(FIT)开发的三维电磁模拟器,可以求解任意几何形状边界条件和自由源的麦克斯韦方程组。作为第一步,采用fdtd型网格。然后,通过FIT将积分形式的Maxwell方程离散为Maxwell网格方程,得到特征模态方程。给定材料属性和边界条件,建立并求解三维几何图形的特征模态问题。
