Abstract:
According to the basic theory of electromagnetic shielding, the theoretical calculation methods and formulas of shielding effectiveness for sheet metal, perforated metal and metal wire mesh were summarized. For different types of fabric or the theoretical calculation model and methods, from perforated metal, wire mesh, topology structure model and other numerical methods, the research progress of the theoretical calculation of shielding effectiveness of electromagnetic shielding fabric in recent years were reviewed. The problems existing in the quantitative research of shielding effectiveness for electromagnetic shielding fabric were analyzed. The view that the theoretical relations between shielding effectiveness and electromagnetic parameters of the yarns, fabric structure need further study was pointed out. In addition, on the basis of the electromagnetic parameters and structure parameters of the yarns, subsequent research direction is to establish analytic formula used to guide the engineering calculation of shielding effectiveness of fabric.
Key words: electromagnetic shielding fabric, fabric, shielding effectiveness, equivalent model, empirical equation, theoretical calculation
