Design of a paper-based reconfigurable frequency selective surface structure

Abstract

In this study, a paper-based reconfigurable frequency selective surface (FSS) that can be applied as wallpaper inside buildings to control the indoor spectrum was designed using the ink-jet printing method. The designed paper-based FSS uses a PIN diode to block 5 GHz band signals in the OFF condition and to transmit the signals in the ON condition, offering frequency characteristics stable to polarization and incident angles. To verify the operation of the designed FSS, the FSS was printed on a 0.2 mm thick paper using the ink-jet printing method by attaching a PIN diode using a conductive adhesive to manufacture the FSS with a switching function. It was confirmed that the measured frequency transmission characteristics according to the switching operation corresponded to the calculated results, and stability was exhibited for polarization and incident angles.

An Amplitude-Modulated Metadevice with Switchable Reflection, Transmission, and Absorption

“…The individual part A loaded on-state diodes are transparent for the EM waves. For state-1, the metadevice acts as an inductive equivalent circuit [ 25 , 29 ]. Both sides of the surface with on-state diodes do not resonate and the surface is transparent to the EM incident waves.…”

“…It switches the three modes by changing the states of diodes with on, off, and resistive, but the harsh current triggering conditions and size limit its practical application. Works on the possibility of switching among transmission, reflection, and absorption utilizing a single metadevice at the same frequency are less, with most research being carried out for only two functionalities: absorption/reflection [ 19 , 20 , 21 , 23 , 24 ], absorption/transmission [ 25 , 26 , 27 , 28 ], or transmission/reflection [ 29 , 30 , 31 ]. Additionally, the limitations of operating bandwidth and efficiency prevent it from being widely used.…”

Wideband frequency reconfigurable antenna array

“…To achieve this performance, many frequency reconfigurable antennas [1,2,3,4,5,6,7,8] and reconfigurable frequency selective surfaces [9,10] with wide tuning ratio were published. They can use switching components such as PIN diodes, varactor diodes, and microelectromechanical systems (MEMS) to provide multi-band operation more easily.…”
