EM Modeling Using SPICE Circuit Solvers
Researchers at Clemson University are combining Finite Element electromagnetic analysis techniques with SPICE circuit solvers to perform fast and accurate electromagnetic simulations. SPICE analysis is generally faster than traditional matrix solvers and can be performed in both the time and frequency domains. FEM-SPICE analysis is also a very effective technique for solving full-wave electromagnetic modeling problems that include linear or nonlinear circuit elements.
Current research is exploring methods for modeling new types of materials and building robust circuit models that are accurate from DC to several GHz.
