Metasurfaces are 2D artificial materials consisting of arrays of metamolecules, which are
exquisitely designed to manipulate light in terms of amplitude, phase, and polarization state …

Abstract In 1987, Yablonovitch and John proposed an artificial dielectric structure known as
Photonic crystals (PhCs) consisting of periodic and random variation of the refractive index …

Fano resonance is a universal phenomenon observed in many areas where wave
propagation and interference are possible. Fano resonance arises from the interference of …

In this paper, a novel 8-shaped resonator coupled to metal–insulator–metal waveguides is
used for designing plasmonic filters and sensors. The resonator supports two resonance …

Herein a numerical analysis is performed to explore the conversion efficiency of mode
converters for a plasmonic waveguide (WG). The major concern of metal-insulator-metal …

One of the fastest-expanding study areas in optics over the past decade has been
metasurfaces (MSs). These subwavelength meta-atom-based ultrathin arrays have been …

This article presents a novel refractive index nanosensor based on a metal–insulator–metal
(MIM) waveguide that incorporates a silver nanorod embedded in a rectangular resonator …

In this article, a novel surface plasmon polariton-based plasmonic refractive index sensor is
proposed and numerically investigated. It consists of a structure of an octagonal cavity …

Surface plasmon resonance (SPR) and surface plasmon polariton (SPP) is substantially
developing optical sensing approaches that have been working in a wide range of …

It is a remarkable and straightforward approach to customize the dispersion and nonlinear
properties of the photonic devices without varying the composition of the material by …
