Independently Tunable Closely Spaced Triband Frequency Selective Surface Unit Cell Using the Third Resonant Mode of Split Ring Slots [PDF]
IEEE Access, 2021 In this paper, a tunable triband frequency selective surface unit cell based on varactor-loaded split ring slots is presented. By using the third resonant mode, a considerable mutual coupling reduction between adjacent ring slots is obtained ensuring both close band response as well as independent band tuning.

Journal of electromagnetic engineering and science, 2010 In this paper, a double-layered frequency selective surface(FSS) superstrate was built and tested. The unit cell of the proposed FSS consists of a ring slot and a dipole-shaped structure and shows a complementary frequency response. Each unit cell is printed on two sides of a substrate.

International journal of RF and microwave computer-aided engineering, 2021 In this study, a frequency selective rasorber (FSR) is proposed where a transmission band at a higher frequency is achieved besides the lower broadband absorption. The FSR is designed by combining the individual designs of broadband absorber and bandpass
