A practical double-sided frequency selective surface for millimeter-wave applications Review of Scientific Instruments 89, 024703 (2018) A new high-performing PCB (Printed Circuit Board) dichroic filter, which can be used for the KSTAR (Korea Superconducting Tokamak Advanced Research) electron cyclotron emission imaging system, is proposed. The current dichroic filter consists of a triangular lattice array of circular holes on the 6-mm thick metal plate, while circular hole spacing limitation caused relatively narrow passband (∼20 GHz). On the other hand, the proposed PCB dichroic filter utilizes the inexpensive commercial PCB fabrication process with a flexible adjustment of circular hole spacing. Therefore, the proposed PCB dichroic filter provides significantly wider passband (∼60 GHz with 0.84 dB insertion loss) with much reduced weight and expense. Also, it is shown that a steep skirt property can be obtained with the thick PCB filter substrate. The design process, fabrication, and measurement results of the new PCB dichroic filter are described. Published by AIP Publishing. [http://dx

In this manuscript, the electromagnetic wave absorption properties of sustainable porous carbon composites were evaluated over the X-band frequency range (8.2-12.4 GHz). The porous carbon material was made from the byproduct of cellulose production and was used as additive on the development of radar absorbing material (RAM) composites. These porous carbon materials have different characteristics, such as porosity size (180 m < Ø 1 < 250 m and 425 m < Ø 2 < 500 m) and particle size (ϕ 1 < 250 m and 250 m < ϕ 2 < 425 m). Composite materials were also studied as frequency selective surface (FSS) structures. It was shown how complex permittivity and reflection loss (RL) can be manipulated over the frequency range using FSS structure. While regular RAM presented RL of 19 dB at ~11.8 GHz, FSS structure presented a RL of 19 dB shifted to 12.4 GHz regarding the same carbon porous material (with particles between 250 and 425 µm and porosity between 180 and 250 µm). It was demonstrated here the potential use of sustainable porous carbon as RAM, and how FSS structure can be used to tune the frequency of the RL maximum peak.

“…They comprise an array of periodic elements on either substrate slots (passband) or patches (stopband) based on specific application. Since from last four decades, FSS shows its potential applications in the field of microwave and millimetre-wave applications such as spatial filters [1], ground plane to the antenna [2], radomes [3] etc. for selected frequency bands.…”

The design of novel ultra‐thin polarisation rotating frequency selective surface based on substrate integrated waveguide (SIW) technology has been presented. The primary function of the structure is to select the linear polarisation from the impinging electromagnetic wave on it and to rotate the wave into the 90° counter‐clockwise direction in the given frequency band. The proposed array consists of periodic Y‐shaped slot elements surrounded by SIW cavities. The structure shows a relative bandwidth of 8% with impedance matching better than −10 dB and a very good insertion loss of 0.3 dB. It also offers co‐polarisation below −20 dB in the passband. The proposed structure is very thin (0.055λ0) compared to the existing SIW‐based frequency selective polarising rotators. Also, the conformal analysis of the proposed structure has been carried to study its behaviour for real‐time applications when used on curved surfaces. Finally, to prove the efficacy of proposed structure, a prototype has fabricated and measured its performance. A very good agreement is observed between the experimental and simulated results.
