| Abstract: | The edge problem of the penetration of the magnetic field pulse with millisecond and microsecond front duration inside a multilayer circular cylindrical shield has been solved by the analytical methods. The mathematical model of the shielding problem is based on the use of the Laplace equation and nonclassical two-sided boundary conditions that connect magnetic fields on both sides of the thin-wall shield. A structure of the magnetic pulse inside the shield and shielding efficiency has been studied numerically depending on the layering structure of the shield at fixed thickness of the shield. |
