A Flexible and Ultrathin FSS for EM Shielding Applications
An ultrathin and flexible frequency selective surface (FSS) is proposed in order to obtain band-stop electromagnetic interference (EMI) shielding. The proposed structure is modeled on flexible ultrathin (polyimide) substrate. Greater than 10 dB attenuation is achieved within the frequency band of 7.79 GHz to 12.57 GHz with maximum attenuation of 60 dB at 10.07 GHz (fractional bandwidth of 46.95%) to provide effective EM shielding. The angular stability up to 45o, polarization insensitivity and ultrathin flexible structure make it a promising candidate for EM shielding applications in X- band.
