Abstract :
For the first time, the FDTD method enhanced with an adaptive mesh refinement (AMR-FDTD) technique, which allows for the field tracking by a moving/rotating 3-D cartesian mesh, is applied to the simulation of microwave integrated circuits. A coarse grid is recursively refined in regions with large gradient of energy. The mesh refinements are dynamically evolving as the simulation progresses. Numerical examples are provided to demonstrate the efficiency of the proposed approach.
