Optimization of Layer Thickness to Yield Predetermined Shielding Performance of Multilayer Conductor Electromagnetic Shield

Electromagnetic shield made up of single conductor layer of chosen thickness and conducting material can be designed to achieve required shielding performance . This single conductor layer electromagnetic shield would be bulky and occupy more volume when the size of the electronic circuit is shrinking with the advent of microelectronic technologies. In order to optimize the thickness of the electromagnetic shield, multilayered conductor electromagnetic shield is designed and developed in this paper. Analysis was carried out of for determination of shielding effectiveness of a multilayer conductor electromagnetic shield after evolving its mathematical model. A design methodology is presented to yield predetermined shielding effectiveness for different materials in various layers of the shield. The designer can be optimizing the layers thickness in the electromagnetic shield for selected conducting materials and shielding effectiveness.
