Flexible and Reconfigurable Frequency Selective Surface With Wide Angular Stability Fabricated With Additive Manufacturing Procedure

Design of broadband dual‐polarised reconfigurable frequency selective surface based on dual‐branch parallel circuit model

“…The RFSSs are mainly altered by external excitations. Comparing with several approaches for realising RFSSs, such as mechanical adjustment [10,11], microelectromechanical systems (MEMS) [12,13], magnetically tunable ferrite [14], liquid crystals [15,16], and active devices [17][18][19][20][21][22][23][24][25][26][27][28][29] such as PIN diodes or varactor diodes, are widely utilised owing to their low cost, compact size, simple fabrication and fast switching speed. The electrically controlled RFSSs can be divided into two categories.…”

“…The electrically controlled RFSSs can be divided into two categories. One is tunable RFSS [17][18][19]; the operating frequencies can shift within a certain frequency range. The other is switchable RFSS [20][21][22][23][24][25][26][27][28][29].…”

An analytical study of curved frequency selective surfaces for shielding applications

“…Frequency selective surface (FSS)‐based structures find numerous applications in EMI shielding, owing to their simple topology, ease of fabrication, and low cost 3–13 . Planar FSSs are usually engineered with different printed circuit board (PCB) techniques, including inkjet printing, 14 and screen printing 15 . However, many practical applications require FSS to be printed on nonplanar or nonuniform surfaces.…”

“…[3][4][5][6][7][8][9][10][11][12][13] Planar FSSs are usually engineered with different printed circuit board (PCB) techniques, including inkjet printing, 14 and screen printing. 15 However, many practical applications require FSS to be printed on nonplanar or nonuniform surfaces. Recent reports in the literature describe FSS geometries on thin flexible substrates as wrapped around nonplanar surfaces.…”
