Metasurfaces, which offer a diverse range of functionalities in a remarkably compact size,
have captured the interest of both scientific and industrial sectors. However, their inherent …

We numerically designed a plasmonic refractive index sensor with high sensitivity and
tunable optical feature based on two metal-insulator-metal bus waveguides connecting with …

The optical properties of plasmon resonant metallic nanoparticles are of great interest
because of their ability to both control optical fields on the nanometer scale and function as …

In this paper, symmetric and asymmetric plasmonic bandpass filter (BPF) topologies based
on the metal–insulator–metal (MIM) configuration are proposed. These filters are …

In this paper, a plasmonic filter based on metal-insulator-metal (MIM) configuration is
proposed. It uses a hexagonal nano-resonator (HNR) coupled to multi-stub waveguides …

Plasmonic demultiplexers using improved circular nanodisk resonators (CNRs) and metal-
insulator-metal waveguides have been designed. The proposed structures use air and silver …

This letter reports a new type of plasmonic metamaterial-based comb filter with the
metasurface as similar to the Salusbury window, and comprised of three layers-sub …

A new design of a highly confined Spoof Surface Plasmon (SSP) line splitter-based
differential phase sensor is presented for the THz frequency region. The position, orientation …

This article is devoted to studying the optical properties of a novel single-crystal LiTi 2 O 4
thin film. A high-quality (011)-oriented LiTi 2 O 4 single-crystal thin film was prepared on a …

In this paper, an enhanced multiparameter sensor based on a metal–insulator-metal (MIM)
waveguide structure with surface plasma polarization is proposed. We initially establish a …
