Abstract: This paper first presents an analytical model for calculating the shielding effectiveness of static magnetic fields using a rotating double-shell cylindrical shield with electromagnetically thin layers made of non-magnetic conducting material. Then a procedure is given for finding the optimum distance between the shells and their thickness for maximum mass reduction compared to a thick single shield for a given shielding factor.

Keywords: Computational electromagnetics, optimization methods, shielding modelling and methods
