Amuneal-Theory & Design-Formulas & Calculations
The attenuation requirements of your specific applications drive the final design of a shield. With a given geometry, we are able to increase the performance of a shield by increasing the thickness of the material. However, if your application requires a more robust shield you can drastically increase your shielding performance by adding additional layers to your shield while maintaining an air gap between each layer.

The following formulas can help you calculate single, dual, and triple-layer shield designs. It is important to note that the value for the permeability of a material used for the purposes of a calculation depends on material composition, shield geometry, and field intensity. Our experienced technical staff is a resource and generous collaborator available to work through these design calculations with you.

Designing and fabricating high-performance magnetic shields begins with understanding the mechanics behind shielding theory.
