Özet
In this study, to filter electromagnetic (EM) frequencies, a multi-frequency frequency-selective surface (FSS) design was developed as smart electromagnetic windows for electromagnetic interference/electromagnetic compatibility (EMI/EMC) applications. The design was based on three main frequency values (flower(1042 MHz),fmiddle(2286 MHz),fupper(2895MHz)). The EM window exhibited opacity at these frequencies and bandstop behavior at others. The designed FSS was analyzed in a full-wave simulator environment, and its transmission/reflection values were obtained to determine its characteristic properties. A current density analysis was conducted, and the relationship between the design and the results was thoroughly explained and discussed. As a result of the study, an FSS capable of operating at three frequencies that allow multi-band operation with return loss below -15dB was obtained.
