access to any solution (more than one parameter)

Hello

When I do a parametric sweep with only one parameter, I can access to one particular solution with the operator "with", for example, with(1,emw.Ez) gives me the z-electric field for the first parameter.

However, If I do a parametric sweep with two parameters, how can I acces to any solution? It should be something like with(1,2,emw.Ez)...or something similar...but I have no idea...

Thank you
