EDA Solution

EM3DS (Electromagnetic 3D Solver) is a novel, full-featured, frequency-domain full-wave simulaton tool tailored to efficiently accomplish the analysis of quasi-planar structures – specifically planar structures over complex substrates, where the finite conductors' thickness and the dielectric discontinuities are accounted for with no compromise – thus, rendering EM3DS a full 3D tool.

Unlike most Method-of-Moment (MoM) solvers available on the market, it uses volume currents to account for conductors and dielectric bricks (generally MoM solvers are 2.5D in their very nature, using only surface currents). Nonetheless EM3DS now implements also a 2.5D engine, making easier and faster to correctly setup robust electromagnetic simulations.

Owing to its generic formulation, the so-called Generalized Transverse Resonance-Diffraction (GTRD) developed by Dr. M. Farina at the University of Ancona, Italy, EM3DS is equally capable of simulating active linear devices, like FETs. This is realized by defining distributed controlled current sources directly in the electromagnetic kernel (no lumped elements!), providing a self-consistent small-signal modeling for high frequency FETs. To the best of our knowledge to date, EM3DS is the only program on the market suitable to conduct such simulation.
