Hi, I know very well that 3D EM modelling is recommended for via and connectors etc if we go for a high speed design. I would like to know how the accuracy is improved if we use 3D EM when the frequency is in GHZ. Please explain the accuracy with frequency with respect to 3D EM. -- Best Regards, Balamanikandan.K ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List forum is accessible at: http://tech.groups.yahoo.com/group/si-list List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
