Abstract
In order to realize fast modeling and simple, efficient solution of the electromagnetic wave distribution in the interconnects of three-dimensional integrated modules, the Alternating Direction Implicit Finite Difference Time Domain (ADI-FDTD) method is used in this paper to reveal the propagation of two-dimensional Transverse Electric (TE) wave. This method can overcome the shortcoming of the conventional FDTD which is limited by Courant-Friedrich-Lewy (CFL) stability conditions, so as to improve the calculation efficiency. Due to the limited storage space of computer, only physical and mathematical models describing the limited space can be established. In order to simulate the propagation process of electromagnetic wave in unbounded or semi-unbounded space, the Mur first-order absorbing boundary condition is applied to ADI-FDTD technology, and the introduction of absorbing boundary condition does not destroy the unconditional stability of time stepping. Finally, an example is given to demonstrate the effectiveness of the algorithm.
