MULTILAYER ELECTROMAGNETIC SHIELD FOR PROTECTING PHOTOMULTIPLIERS AND METHOD FOR DEPOSITION THEREOF Russian patent published in 2013 - IPC G12B17/02 H05K9/00 H05K5/06 

Abstract RU 2474890 C1

FIELD: physics.

SUBSTANCE: multilayer electromagnetic shield according to the invention is in form of a coating of successively deposited magnetic and nonmagnetic layers, wherein the thickness of the nonmagnetic layer is selected in the range of 1-25 mcm, the thickness of the magnetic layer is selected in the range of 6-250 mcm, wherein the total thickness of the magnetic layers is 300-500 mcm and the total number of magnetic and nonmagnetic layers is in the range of 3<Nmagn+Nnonmagn<99, wherein Nmagn=Nnonmagn+1.

EFFECT: high manufacturability and low cost of making the multilayer electromagnetic shield, minimising weight and size characteristics with high protective properties.
