Modeling & Simulation Analysis of Frequency Selective Fabrics (FSF) for evaluation of its Shielding Effectiveness in GSM band

Frequency selective surface (FSS) is a repeated structure which can transmit, reflect or absorb the incident electromagnetic wave based up on the application interest using patches or slots. The patch and slot arrays effectively create band stop and band pass filters. The FSS have potential applications in providing sufficient Shielding in the desired frequency ranges. The work proposed in this paper is to study & analyze the FSS structural requirements to shield against the GSM band frequencies. The persons working near the mobile towers are exposed to strong EM fields, hence they need to guard themselves against these fields. The concept of FSS is extended to print the structures on the plane fabrics, and the same can be worn by the working personnel. The paper is primarily based on the simulation analysis of the designed fabrics using EM software tools. The simulation results are validated using experimental results.
