[SI-LIST] : Freq. dependent losses in Spice?

Hi,

I am curious if anyone has any experience using the LAPLACE operator in
PSpice to represent frequency dependent T-line losses (e.g. skin
effect)? Also could you provide some insight into your implementation
methods? The PSpice manual suggests using the Laplace operator to
describe R and G in their lossy T-line model, but no suggestions for
implementation.

I have read a number of papers (some from members of the SI-LIST)
regarding the use of RL ladder networks to simulate skin effect losses
and have tried them with some very good luck. I am just curious if
anyone has attempted the method that Microsim has suggested and why they
have opted for a different method.

Thanks for any help!
