TL;DR: In this article, the optical effect of the substrate on the anomalous absorption of aggregated silver films is taken into account in terms of the dipole interaction between an island particle and its mirror image in the substrate.

TL;DR: In this article, a simple equation for the anisotropic dielectric constant of a metal island film is derived and applied to the ellipsometric measurement for an aggregated silver film.

TL;DR: In this paper, the complex dielectric constant of an aggregated metal film is represented by the equation e−e = q e i −e a 1+ ƒ(e i − e a ) e a ǫ = −0.36 d w α for an electric field parallel to the substrate.

TL;DR: In this article , a tensile experiments of model root structure fabricated with 3D printers were conducted to elucidate the pull-out mechanisms of plant roots from soil, and they found that the maximum pullout force is dependent on the branch angle and the bending stiffness of the roots.

TL;DR: In this paper , a metamaterial structure using bars, discs, springs, and bolts was constructed and in-situ tensile experiments were conducted to elucidate the static and dynamic behaviors of mechanical metammaterials.
