Hi,
My posting below (from last December) proved quite popular so we polished it up
into a white paper:
http://cp.literature.agilent.com/litweb/pdf/5990-5266EN.pdf
On a related note, the on-demand version of Eric's webinar, which includes info
about models of lossy dielectrics that conform to Kramers-Kronig causality, is
here:
http://www.bethesignal.net/bogatin/nma850-frequencydependent-material-properties-p-430.html
The webinar is based on our DesignCon 2010 paper that Eric has posted here:

Subject: [SI-LIST] Kramers-Kronig in Pictures
Hi,
Thanks to Eric Bogatin for pointing out a neat proof of the Kramers-Kronig
relation in his excellent book review:
http://bethesignal.net/blog/?p=63
...of Hall and Heck's excellent book.
After some reading and doodling, a little light bulb lit up, and the result was
my latest blog posting "Kramers-Kronig in Pictures" here:
http://signal-integrity.tm.agilent.com/2009/kramers-kronig-in-pictures/
The Kramers-Kronig relation is very useful in SI because it enables you to
determine time-domain causality (or lack thereof) of a frequency domain model
(e.g. s-parameters) before you attempt to move it into the time domain. IMHO,
it's worth getting to know.
