What is CuToo-FD ?

CuToo-FD is a comprehensive simulation platform for the electromagnetic field analysis of 3D structures. It is based upon a full-wave FDTD 3D electromagnetic simulation software for the solution of Maxwell’s equations, enabling user to solve a wide range of electromagnetic problems encountered in industries.

Typical applications

  • Electromagnetic coupling and interference (EMC, EMI): EMC problems analysis : shielding effectiveness of enclosure, cable coupling analysis in complex environment (wiring in aircraft or car), radiation hazard analysis
  • Antenna placement: Analysis of antenna radiation pattern, radiation hazard zones with an antenna placed on a large structure (e.g. ship, aircraft…)
  • Bio-electromagnetics: Analysis of homogeneous or non-homogeneous bodies, SAR extraction
