Creating materials with a desired refraction coefficient: numerical experiments [PDF]
arXiv, 2010 A recipe for creating materials with a desired refraction coefficient is implemented numerically. The following assumptions are used: \bee \zeta_m=h(x_m)/a^\kappa,\quad d=O(a^{(2-\kappa)/3}),\quad M=O(1/a^{2-\kappa}),\quad \kappa\in(0,1), \eee where $\zeta_m$ and $x_m$ are the boundary impedance and center of the $m$-th ball, respectively, $h(x)\in C(D)

Synthetic Active Liquid Crystals Powered by Acoustic Waves
Advanced Materials, EarlyView.A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

Influence on extracted complex refractive index from phase inaccuracy of reflection-type THz-time-domain spectroscopy [PDF]
arXivReflection-type terahertz (THz) time-domain spectroscopy (THz-TDS) enables the measurement of optical properties of opaque samples in the THz frequency range, e.g., carrier density and mobility. In this study, we examine the influence of phase inaccuracy on the extracted complex refractive index from reflection-type THz-TDS.

Advanced Materials, EarlyView.Laser micropatterning is presented as a promising technology in the search for autonomous dew water harvesting materials. Laser‐grooved metallic surfaces achieve simultaneously high infrared emissivity and superhydrophilicity, which gives them self‐cooling properties under atmospheric radiative deficit and the ability to condense water in an efficient ...
