Surface-enhanced Raman spectroscopy (SERS) is a vibrational spectroscopy technique that
enables specific identification of target analytes with sensitivity down to the single-molecule …

Over more than 40 years since its discovery, surface‐enhanced Raman scattering/
spectroscopy (SERS) has attracted substantial attention as a tool for fundamental research …

In this paper, an ultra-broadband perfect absorber based on a four-layer pyramid
metamaterial and a metal insulator metal (MIM) structure has been demonstrated and …

The structural characteristics of plasmonic nanostructures directly influence their plasmonic
properties, and therefore, their potential role in applications ranging from sensing and …

This paper proposes an ultra-broadband absorber numerically demonstrated with the finite-
difference-time-domain method (FDTD). The absorber is composed of a bottom layer of …

This article presents a compact, cost-effective, and contactless fractal modified
electromagnetic bandgap structure (EBG)-based microwave sensing platform for dielectric …

We theoretically study plasmonic antennas featuring areas of extremely concentrated
electric or magnetic field, known as hot spots. We combine two types of electric-magnetic …

We propose an ultra-broadband metamaterial absorber composed of a four-headed arrow-
shaped top layer and titanium-bottom film spaced by a dielectric layer. The absorber attains …

Abstract Surface Enhanced Raman Spectroscopy (SERS) is a popular method that amplifies
weak Raman signals from Raman-active analyte molecules making use of certain specially …

The superhydrophilic surfaces have many important practical applications such as
antifogging, antifouling, self-cleaning, etc. The present study demonstrates a simple and …
