Sparse electromagnetic shields obtained from wire grid
DOI: 10.21293/1818-0442-2025-28-4-13-19
Abstract: Reducing the mass and area of electromagnetic shielding is important for a range of radio electronic devices. To achieve this goal, an optimal current grid approximation (OCGA) for creating sparse shields is presented for the first time. The sparse shields were obtained from a square wire grid (WG), using OCGA with grid element elimination tolerances (GEET) of 2, 5, 20, and 30%. Their characteristics were analyzed in comparison with the original WG shield. Frequency dependencies in the 10–1000 MHz range, as well as distance‑ dependent variations for the electric and magnetic field strengths and shielding effectiveness are presented. The optimal GEET of 20% was selected, resulting in a 2.1-fold mass reduction and acceptable performance tolerances.
Keywords: method of moments, shielding effectiveness, electromagnetic compatibility, sparse shield, wire grid, mass reduction, optimal current grid approximation
