i wonder how come the electric flux doesn't depend on the MATERIAL that the area which the Electric field goes through is made of?>?>>??>

The surface through which the electric field passes through is imaginary, just as what you would expect from Gauss law. The magnitude of the electric field at the surface may depend on the material it is passing through but once you have taken that into account, the flux is simply the dot product of net electric field through that surface.

so are there any constants for each material "permeability" of electric field... :)

or u are saying that the general idea is that the E field is always the dot product... regardless the surface.. :) or something like that... i just started studying electricity and I am kinda lost yet :)
