We designed and fabricated a terahertz (THz) frequency selective surface (FSS) based on two distinct additive manufacturing technologies, namely, printable electronics (PE) three-dimensional (3D) printing. Silver nanoparticle ink was printed polyethylene terephthalate (PET) substrate utilizing large-scale roll-to-roll industrial PE technique with flexographic unit, while the 3D-printed THz FSS ...

In this paper, a three-layered frequency-selective absorber (FSA) that can efficiently absorb electromagnetic waves (EM) in double-band is proposed. The proposed structure designed so signals reflected from the frequency selective ground plane are located at 2.4 and 5.5 GHz (ISM UNII bands) absorbed by front resistive layers. Simulation results show not only blocks transmission desired bands bu...
