“…While an individual origami can serve as a template for up to 200 small devices, typically only a single multi-component electronic or optical device is constructed 10,12 . For many technological applications it would be desirable to organize origami into periodic arrays, for example, to allow wiring of electronic devices together, to create cooperative optical effects as seen in optical metasurfaces 17 , to create DNA 'etch masks' 18,19 or to enable easier extraction of single-molecule biophysical data 9,20 .…”

DNA origami has proven useful for organizing diverse nanoscale components into patterns with 6 nm resolution. However for many applications, such as nanoelectronics, large-scale organization of origami into periodic lattices is desired. Here, we report the self-assembly of DNA origami rectangles into two-dimensional lattices based on stepwise control of surface diffusion, implemented by changing the concentrations of cations on the surface. Previous studies of DNA-mica binding identified the fractional surface density of divalent cationsñ s2 ð Þ as the parameter which best explains the behaviour of linear DNA on mica. We show that for n s2 between 0.04 and 0.1, over 90% of DNA rectangles were incorporated into lattices and that, compared with other functions of cation concentration,ñ s2 best captures the behaviour of DNA rectangles. This work shows how a physical understanding of DNA-mica binding can be used to guide studies of the higher-order assembly of DNA nanostructures, towards creating large-scale arrays of nanodevices for technology.

“…The recently proposed metasurface is a two-dimensional array of subwavelength scatterers [1][2][3][4][5][6][7][8][9]. It is a promising way to manipulate electromagnetic (EM) wave propagation because of the designable feature of its surface impedance, which uniquely determines the EM field behavior.…”

Abstract-Metasurfaces, due to its designable surface electric and magnetic impedances, have largely enhanced electromagnetic wave manipulation techniques. The conventional approach to realize the surface magnetic impedance requires non-planar structures, such as metallic loops, which is not easy to fabricate, especially at optical frequencies. In this work, we theoretically and rigorously prove that effective surface magnetic and electric impedances can be obtained using parallel electric metasurfaces. A synthesis method is presented which allows independent designs of surface electric and magnetic impedances. Finally, a polarization converter with high energy efficiency is designed using the proposed impedance synthesis method for verification. The proposed synthesis method is favorable for reducing fabrication complexities.

“…Metamaterials, which are commonly composed of numerous electrically small scatterers arranged in a regular or irregular layout, are broadly defined as artificially homogeneous or inhomogeneous electromagnetic structures with unusual properties that are not available in nature [1][2][3][4]. Metasurface, a two-dimensional equivalent of metamaterial, has been attracting attention of researchers in the past few years.…”

Abstract-A new circularly-polarized metasurfaced dipole antenna (MSDA) with wide axial-ratio (AR) beamwidth and radar cross section (RCS) reduction properties is proposed and studied in this paper. This antenna is a quite simple half-wavelength linear dipole right above a metasurface which consists of 9 double-head arrow-shaped unit cells arranged in a 3×3 layout. By cautiously choosing the geometrical parameters of the metasurface and tuning the distance between the dipole and the metasurface, the whole structure turns out to be a circularly-polarized antenna with RCS reduction feature. Simulation results show that the MSDA in circular polarization achieves an operating bandwidth of 410 MHz and a wide AR beamwidth of 123 • and 90 • in ϕ = 0 • and ϕ = 90 • planes respectively, together with a maximum RCS reduction of 10.4 dB in the whole operating band.
