“…[5][6][7][8] Therefore, an infrared transparent FSS (ITFSS), which possesses high transmittance in infrared band for imaging sensor and band-pass effect in millimeter wave band for receiving radar signal, needs to be developed. In earlier work, [9][10][11][12] we have demonstrated an ITFSS structure by integrating the cross-slot units on the square metallic meshes (noted as standard ITFSS). Experimental results show that the standard ITFSS has an average transmittance of 76% with a MgF 2 substrate in the infrared band and a stable band-pass behavior in the millimeter wave band with a transmittance of −0.56 dB.…”

In this paper, we present an infrared transparent frequency selective surface (ITFSS) based on iterative metallic meshes, which possesses the properties of high transmittance in infrared band and band-pass effect in millimeter wave band. Cross-slot units are designed on the iterative metallic meshes, which is composed of two same square metallic meshes with a misplaced overlap. In the infrared band of 3–5 μm, the ITFSS has an average transmittance of 80% with a MgF2 substrate. In the millimeter wave band, a transmittance of −0.74 dB at the resonance frequency of 39.4 GHz is obtained. Moreover, theoretical simulations of the ITFSS diffractive characteristics and transmittance response are also investigated in detail. This ITFSS may be an efficient way to achieve the metamaterial millimeter wave/infrared functional film.

A novel wideband, low-profile and second-order miniaturized band-pass frequency selective surface (FSS) made of metallic mesh and its complementary structures with skewed arrays of modified triples is presented in this paper. Compared with traditional second-order bandpass FSSs obtained using λ/4 apart from one another, the novel FSS with an overall thickness of λ/18 is composed of three metallic layers (the outside and middle layers are complementary) separated by two electric thin dielectric substrates. This arrangement can shorten the inter-element spacing and increase the bandwidth, while the up and bottom metallic layers can constitute a symmetric biplanar FSS and thus realize ability of maximally flat second-order bandpass response. The novel FSS has a −3 dB bandwidth about 8.2 GHz (6.9 -15.1 GHz) and a fractional bandwidth exceeds 75%. Moreover, such an FSS has the merits of stable performance for incident angles within 50° and different polarizations. The principles of operation along with guidelines for the design of the proposed FSS, the simulated results by vector modal matching method, and the experimental values of the fabricated prototype are also presented and discussed.
