EMC’04/Sendai MODELLING TECHNIQUES FOR THE CALCULATION OF THE SHIELDING EFFECTIVENESS OF EQUIPMENT CABINETS
The paper describes recent advances in the modelling and simulation of materials and screens for the shielding and absorption of EM waves. Simple intermediate models are briefly outlined, followed by models for describing complex materials and screens in the time-domain.
متن کاملShielding Effectiveness Simulation of Small Perforated Shielding Enclosures Using FEM
Numerical simulation of shielding effectiveness (SE) of a perforated shielding enclosure is carried out, using the finite element method (FEM). Possibilities of model definitions and differences between 2D and 3D models are discussed. An important part of any simulation is verification of the model results—here the simulation result are verified in terms of convergence of the model in dependenc...
متن کاملShielding Effectiveness of a Lossy Metallic Enclosure
In this paper, shielding effectiveness (SE) of a perforated enclosure with imperfectly conducting walls is evaluated. To this end, first, an accurate numerical technique based on method of Moments (MoM) ispresented. In this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. Then, the impedance boundary condition on the imperfectly conductin...

متن کاملMeasuring Space Radiation Shielding Effectiveness
Passive radiation shielding is one strategy to mitigate the problem of space radiation exposure. While space vehicles are constructed largely of aluminum, polyethylene has been demonstrated to have superior shielding characteristics for both galactic cosmic rays and solar particle events due to the high hydrogen content. A method to calculate the shielding effectiveness of a material relative t...
