Low frequency emission simulation using 3D electromagnetic solver based on CISPR25

This study was performed to investigate correlativity between the simulation results and the actual measurement on emission from electric wire in the low frequency band (150 KHz ~ 30MHz) specified in CISPR25. Only a few reports were available on the similar study because the scale of electromagnetic (EM) simulation became too large to maintain the resource of PC. However, there have been growing demands for case studies using EM simulation when designers make a layout. In this study, Hybrid simulation combining the 2 Dimension Transmission Line (2DTL) (Ref. 1) method and the Finite Integration Technique (FIT) (Ref. 2) enables the efficient simulation. High-end workstation with a multi GPGPU system supports the study to keep the sufficient memory.
