New Finite Difference Time Domain (νFDTD) Electromagnetic Field Solver

With the advent of sub-micron technologies and increasing awareness of Electromagnetic Interference and Compatibility (EMI/EMC) issues, designers are often interested in full-wave simulations of complete systems, and of their possible environments. Such simulations can be very complex, especially when the problems of interest involve multi-scale geometries with very fine features. Under these circumstances, even the well-established methods either in the time or frequency domains, such as the Finite Difference Time Domain (FDTD), Finite Element Method (FEM), or the Method of Moments (MoM), are often challenged to the limits of their capabilities. The nu (use symbol for nu) FDTD solver is an approach which is being proposed to handle such challenges. The nu (use Symbol for nu) FDTD is a hybridized version of the conformal FDTD (CFDTD) and a novel frequency domain technique called the Dipole Moment Approach (DM Approach). We show that this blend of time domain and frequency domain techniques empowers the solver to solve a wide variety of problems in a numerically efficient way.
