【Abstract】 A EBG type of electromagnetic shielding fabric made of metal was proposed.The finite difference time domain method was used to calculate the band gap,which showed that the band gap was large with its shielding efficiency reaching to 40dB.The conductivity had a little affect on the cut-off frequency whilst the plot ratio exerted a large affect on the cut-off frequency.The depth of electromagnetic shielding fabric affected shielding efficiency a little.更多还原
