ARTIFICIAL MOLECULE REALIZATION OF A MAGNETIC WALL

The design of magnetic materials can be achieved with artificial magne tic molecules formed by electrically small loop antennas loaded with p assive electrical circuit elements. A time derivative Lorentz material response is achieved with a series resistor and capacitor load. It is shown that the parameters of this magnetic molecule can be selected t o yield a time derivative Lorentz material that acts as a highly condu cting magnetic wall.
