In addition, the possibility of implementing the necessary supporting structures on the installation site and the available space are also determining factors for magnetic shielding design.
To properly design magnetic shielding, Itel Telecomunicazioni uses a specialized software solution called “Vector Fields OPERA”, developed by Vector Fields, a leading company in the field of simulation software solutions for electromagnetic fields. OPERA applies the method of “finite elements” in order to solve differential equations for partial derivatives, which describe the behavior of electrical and magnetic fields. The actual model is thus split into various steps as follows:
Physical model: individuation of the specific features of the electromagnetic problem, in terms of geometry and materials, characterized by first magnetization curves, which are certified by competent bodies.
Geometric model: geometry reduction considering its active parts related to the electromagnetic problem.
Mathematical model: individuation of potential type and surrounding conditions.
Thanks to powerful work stations, it is possible to simulate and optimize magnetic shielding thickness, in order to comply with project certifications relating to dispersed magnetic induction field, while ensuring field homogeneity in the whole volume of the investigated object.
