Multiple resonance modes in an optical absorber are necessary for nanophotonic devices and encounter a challenge the visible range. This article designs multiple-channel plasmonic metamaterial (PMA) that comprises hexagonal arrangement of metal-shell nanorods unit cell over continuous thin metal layer, operating range sensitive refractive index (RI) temperature applications. Finite element method simulations utilized to investigate physical natures, such as absorptance spectrum, magnetic flux surface charge densities, electric field intensity, electromagnetic power loss density. The advantage proposed PMA is it can tune either three or five channels with narrowband recorded sensitivity figure merit (S, FOM) 1-5 be obtained (600.00 nm/RIU, 120.00), 120.00 RIU-1), (400.00 50.00 (350.00 25.00 respectively.

Abstract Kirigami, the ancient art of paper cutting, has evolved into a design and fabrication framework to engineer multi‐functional materials structures at vastly different scales. By slit cutting with carefully designed geometries, desirable mechanical behaviors—such as accurate shape morphing, tunable auxetics, super‐stretchability, buckling, multistability—can be imparted otherwise inflexible sheet materials. In addition, kirigami provides versatile platform for embedding electronic responsive components, opening up avenues building next generations metamaterials, sensors, soft robotics. These promising potentials kirigami‐based engineering have inspired vigorous research activities over past few years, generating many academic publications. Therefore, this review aims provide insights recent advance in vibrant field. particular, offers first comprehensive survey unique properties induced by their underlying physical principles, corresponding applications. The synergies between methodologies, mechanics modeling, advanced fabrication, material science will continue mature discipline.

One of the fastest-expanding study areas in optics over past decade has been metasurfaces (MSs). These subwavelength meta-atom-based ultrathin arrays have developed for a broad range functions, including lenses, polarization control, holography, coloring, spectroscopy, sensors, and many more. They allow exact control properties electromagnetic waves. The performance MSs dramatically improved because recent developments nanofabrication methods, this concept to point that it may be used commercial applications. In review, vital topic sensing considered an up-to-date carried out. Three different kinds MS absorber sensor formations, all-dielectric, all-metallic, hybrid configurations, are presented biochemical We believe review paper will provide current knowledge on state-of-the-art devices based MSs.
