I've tried this web page several times in the past year and I always get the same message: Missing Referrer - Access Denied Your browser did not send a Referer header with this request, so it is not possible to check that the referring page is allowed to access this program. I cannot send them a note either, asking for help. I again get the same message. Any clues on how to get it to work? I've tried different computers, different browsers, removed firewalls, etc. Tom Dagostino Teraspeed Consulting Group LLC Teraspeed Consulting Group LLC 2926 SE Yamhill St. Device Modeling Division Portland, OR 97214 13610 SW Harness Lane Beaverton, OR 97008 http://www.teraspeed.com 503-430-1065 tom@xxxxxxxxxxxxx -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]On Behalf Of Robert Nowak Sent: Thursday, November 13, 2003 12:00 AM To: si-list@xxxxxxxxxxxxx; ludwig@xxxxxxxxxxxxxxxxx Subject: [SI-LIST] Antw: Scattering parameters for "typical" vias Hi Stefan, You can download fasthenry (a 3D inductance extraction program) from http://www.fastfieldsolvers.com/ for free. I hope that help you. Greatings, Robert >>> Stefan Ludwig <ludwig@xxxxxxxxxxxxxxxxx> 11/12 9:23 >>> Hi, does anybody know of a place where one can get scattering parameters (s2p files) for "typical" vias used in current FR-4-based PCBs? By typical I mean max. of 1:10 ratio (drill hole size vs. PCB thickness) vias. I know that there are many variables involved, like number of power planes, pad sizes, through-hole vs. back-drilled vs. buried vs. laser, etc., so any pointers would be appreciated. Unfortunately, I don't have a 3D solver at hand, with which I could model this. Thanks!
