Conducted Emissions
Conducted Emissions Simulations
Conducted electromagnetic energy in EMC terms refers to electromagnetic energy that gets coupled onto an electrical or electronic device's power, signal cable, or other conductive circuitry. Conducted emissions from the standpoint of the equipment under analysis, refers to electromagnetic energy generated by the device and directed away from it.
​
The simulation method for conducted emissions at Lagwaves includes a LISN per measurement standards, and a procedure for extracting the EMI signature from a transient time-domain simulation, while also coupling to a 3D full-wave environment for radiation characteristics of cables and other elements. Simulation of electromagnetic interference (EMI) eliminates the ‘black magic’ of EMI design, enables the use of optimization techniques, and reduces the risk of product delays.
