TL;DR: In this paper, a new method for designing low profile frequency selective surfaces (FSS) with second-order bandpass responses is presented, which utilizes non-resonant subwavelength constituting unit cells with unit cell dimensions and periodicities in the order of 0.15 lambda 0.30.

TL;DR: In this paper, the authors present a comprehensive synthesis procedure for designing low profile, band-pass frequency selective surfaces composed of non-resonant constituting elements, which can provide sharp frequency selectivity and stable frequency responses as functions of angle and polarization of incidence of the EM wave.

TL;DR: In this article, a technique for designing low-profile planar microwave lenses consisting of numerous miniature spatial phase shifters distributed over a planar surface is presented, where the topology of each SPS is based on the design of a class of bandpass frequency selective surfaces composed entirely of sub-wavelength, non-resonant periodic structures.

TL;DR: In this paper, a low-profile, ultrawideband, true-time-delay (TTD) equivalent microwave lenses are designed, fabricated, and experimentally characterized at X-band.

TL;DR: In this paper, a three layer structure composed of three metal layers, separated by two electrically thin dielectric substrates, is proposed for conformal frequency selective surfaces. But, unlike traditional third-order bandpass FSSs, which are usually obtained by cascading three identical first-order frequency selective surface (FSSs) a quarter wavelength apart from one another and have thicknesses in the order of lambda/2, the proposed structure has an extremely low profile and an overall thickness of about lambda/24, making it an attractive choice to conformal FSS
