Abstract :
This paper presents a method of coupling a quasistatic field solver with the finite-difference time-domain method for the more efficient modeling of multilayer packaging structures including metal and dielectric loss effects. Lossy metal characteristics are first simulated with a dense quasistatic grid and the resulting field correction factors are then used to enhance the accuracy of a much coarser FDTD mesh.
