EMI/EMC simulation with Efield®
The electromagnetic environment is becoming more and more complex.
The EMC problem consists of modelling and understanding the
penetration of EM-fields into objects and analyzing the coupling
to internal cables or bundles.
The Efield® time-domain FDTD and hybrid FDTD-FEM solvers are superb
choices for EMC/EMI analysis enabling broadband modeling.
EMI/EMC simulation examples with Efield®
Lightning is a major threat to any complex system containing sensitive
electronic equipment. Simulations are preferably performed in the
time domain. Field penetration into the interior of an aircraft
and the corresponding induced wire currents are examples of studies
that can be performed with Efield®.
An important area is unwanted interference with EM fields
generated by external and sometimes internal sources. Such fields may
propagate as radiation through space or along conducting structures.
The frequencies may range from very low (kHz) up to very high (tens of GHz).
The penetration mechanisms as well as the test setups can be modeled by
