To give an idea about the dielectric properties of metals, an experimental setup must be there for students. I am looking for an easy and cheaper set up to be installed in the lab.
Actually the two references cited above are identical. The attached file is good but does not respond to the question, which is rather philosophical: what is the dielectric property of a METAL, which is a conductor? If one looks at the complex impedance a piece of metal is well characterized by a resitor - without any capacitor. In fact, it is not possible to build a condenser if we put a consuctor between the capacitor plates, as there will be no BOUND charges, only mobile ones, therefore the charge will more form one electrode to the other. I wonder hat the theoreticla physicists tell about this problem. Is it possible to defien the dielectric porperty of metals???
The following application note can be helpful (page 17) :
