Natural white silk cocoons exhibit strong broadband optical scattering by Anderson localization within the silk fibers, providing a low‐light environment to the pupae inside. This scattering effect is due to thousands of densely packed parallel fib

Cyphochilus white beetles possess an exceptional ability to scatter visible light from their scales, which have anisotropic nanofibrillar network structures. We discover a striking effect that diffusely incident light on the beetle scales is preferen

We develop a model to describe the optical properties of periodic surpentine structures in the metamaterial regime. The structures are essentially transparent to infrared radiation and would be useful for transparent electrodes. The model predictions

The present paper aims to investigate some semi-separation axioms relating to the Alexandroff one point compactification (Alexandroff compactification, for short) of the digital plane with the Marcus-Wyse ($ MW $-, for brevity) topology. The Alexandr

The purpose of the paper is to study digital topological versions of typical topological groups. In relation to this work, given a digital image $ (X, k), X \subset {\mathbb Z}^n $, we are strongly required to establish the most suitable adjacency re

Since the Marcus-Wyse ($ MW $-, for brevity) topological spaces play important roles in the fields of pure and applied topology (see Remark 2.2), the paper initially proves that the $ MW $-topological space satisfies the semi-$ T_3 $-separation axiom

The paper aims at developing the most simplified axiom for a pseudo (k0, k1)-covering space. To make this a success, we need to strongly investigate some properties of a weakly local (WL-, for short) (k0, k1)-isomorphism. More precisely, we initially

The paper initially develops the semi-Jordan curve theorem on the digital plane with the Marcus-Wyse topology, i.e., $ MW $-topological plane or $ ({\mathbb Z}^2, \gamma) $ for brevity. We first prove that while every simple closed $ MW $-curve is se
