Epsilon-near-zero (ENZ) materials have attracted much interest within the photonics community due to various novel light-matter interactions that can occur in ENZ regime. These display a large impedance mismatch between material and free space, making it difficult couple light into medium at normal incidence. In this article, we demonstrate enhanced coupling an metamaterial stack be achieved vi...

Biocompatibility of biomedical devices can be improved by endothelialization of blood-contacting parts mimicking the vascular endothelium's function. Improved endothelialization might be obtained by using biomimetic coatings that allow local sustained release of biologically active molecules, e.g. anti-thrombotic and growth-inducing agents, from nanoliposomes. We aimed to test whether incorpora...

The flat plate solar collector (FPSC) is a well-known energy harvesting tool that minimizes the strain on traditional production approach while also promoting future use of renewable energy. Thus, Increasing performance this worth effort. As world's consumption continues to grow, there has been an increased focus potential for nanotechnology improvements reduce usage. Recent scientific research...

A matrix $Pintextmd{C}^{ntimes n}$ is called a generalized reflection matrix if $P^{H}=P$ and $P^{2}=I$‎. ‎An $ntimes n$‎ ‎complex matrix $A$ is said to be a reflexive (anti-reflexive) matrix with respect to the generalized reflection matrix $P$ if $A=PAP$ ($A=-PAP$)‎. ‎In this paper‎, ‎we introduce two iterative methods for solving the pair of matrix equations $AXB=C$ and $DXE=F$ over reflexiv...

Three potential techniques for texturing commercial multicrystalline silicon solar cells are compared on the basis of reflectance measurements. Wet acidic texturing, which would be the least costly to implement, produces a modest improvement in reflection before antireflection coating and encapsulation, whereas maskless reactive-ion etching texturing, and especially masked reactive-ion etched p...

The fine structure of the wing scale of a Morpho Peleides butterfly was examined carefully, and the entire configuration was completely replicated by a uniform Al(2)O(3) coating through a low-temperature ALD process. An inverted structure was achieved by removing the butterfly wing template at high temperature, forming a polycrystalline Al(2)O(3) shell structure with precisely controlled thickn...

Porous silicon is an important material for a variety of application area such as anti-reflective coating solar cells. Today, cell market mostly dominated by based thin films are easy to fabricate and it compatible with technology. Designing porous layers critical issue enhance performance. There several methods calculate reflection coefficient layers. In this study, transfer matrix method fini...
