perfect magnetic conductor

i am trying to use PMC in my simulation. there is built in PEC in the simulation software but no PMC.
now i am wondering how can i model PMC ?
what properties should i assign to the PMC block?
i can specify the following properties in my simulation package

permitivity
permeability
electric conductivity
electric loss tangent
magnetic conductivity
magnetic loss tangent

i would appreciate if someone tell me the properties to be assign to PMC.

regards

PEC is a conductor with an infinite conductance (zero resistance). The analogue of "magnetic circuit" is: a magnetic material with a zero reluctance.
