MEFiSTo-3D Pro™

Time Domain Electromagnetic CAD Tool from DC to Daylight

MEFiSTo means “Multi-purpose Electromagnetic Field Simulation Tool”. This full-wave volumetric time-domain simulator addresses the requirements of design engineers, researchers and educators working with RF/microwave/optical analog and high-speed circuits, antennas, EMC/I, RF heating and biomedical applications of electromagnetic fields. It features robust high-performance TLM numerical engines that provide second-order accuracy and have superior dispersion properties. TLM uses an unconditionally stable scattering algorithm rather than a finite difference model to solve Maxwell’s equations. Circuits & devices modeled by SPICE or MATLAB can be embedded in 2D and 3D field space. Data can be co-processed on-the-fly and visualized either in real solution time, or post-processed.

MEFiSTo is a virtual Time Domain Reflectometer, a Microwave Vector Network Analyzer, an Antenna Range, a Spectrum Analyzer, a Signal Processor, and a Video System all at once. It runs on Windows XP and higher platforms. 32-bit and 64-bit versions are available.

 MEFiSTo Capabilities

MEFiSTo-3D Pro™ is an autonomous EM CAD tool that provides, at the same time, unprecedented interconnectivity with external simulation/data processing/control software. This gives you the freedom to create your own sophisticated modeling environment and to expand the range of modeling capabilities beyond the bounds of mainstream electromagnetic solvers with restricted user access.
