Electromagnetic shielding for electromagnetic launch

2012 16th International Symposium on Electromagnetic Launch Technology, 2012
With the basic principle of magnetic circuit, the effect of the permeability and conductivity of the coil electromagnetic launcher (EML)'s shielding material on the launching performance was investigated. The model of the coil EML was set up in Ansoft Maxwell, and the influence of thickness and the structure of the shield on the launching process were ...

Effective electromagnetic shielding

IEEE Microwave Magazine, 2006
Electromagnetic pollution has been categorized as a new form of pollution. The ability to reflect electromagnetic energy can be defined as shielding effectiveness. This shielding effectiveness depends on the frequency of the electromagnetic wave and the electromagnetic properties of the shielding material.

Electromagnetic pulse shielding

IEEE Transactions on Magnetics, 1979
The limiting nonlinear analysis of Sixtus and Tonks[1] is extended to the prediction of the shielding effectiveness of soft magnetic materials subjected to electromagnetic pulses. The magnetization curve is approximated by N steps in which magnetic induction or intensity varies but both never vary simultaneously.
