Eliminating the Low-Frequency Breakdown Problem in 3-D Full-Wave Finite-Element-Based Analysis of Integrated Circuits

An effective method is developed in this work to extend the validity of a full-wave finite-element-based solution down to dc for general 3-D problems. In this method, we accurately decompose the Maxwell's system at low frequencies into two subsystems in the framework of a full-wave-based solution. One has an analytical frequency dependence, whereas the… CONTINUE READING
