Hi, Sergio.I'm not sure I understand the question - or the problem - so maybe
others don't either.
If you're inverting (FDEM), the input is in-phase and quadrature (normally) and
apparent conductance (conductivity-thickness product, or CTP) is a product
along with the other plate parameters.
If you're forward modeling, the conductivity is an input as part of the CTP,
and the EM response is the product, or output. From that EM we can estimate a
CTP (and then assign a thickness to get conductivity), but that derived CTP
depends on the plate model used. Changes in the size of the plate
(particularly the minimum dimension) change the phase angle (or decay constant
in TDEM) and therefore the estimated apparent CTP and conductivity.
Of course, when forward modeling you can use the size of the model plate in
your calculation of apparent conductance, but then you should get back the
initial model conductance (in the absence of other interfering factors, like
host response).
So, what kind of model are you running, and what are you trying to get out of
it?

Re: Question about plate modeling with Maxwell
Dear all,
It has been a while since I worked last with Maxwell.
Do you know whether we can model plates with just the calculated apparent
conductivity and without the in-phase and quadrature amplitudes?
