Purpose This paper aims to focus on research work related to metamaterial-based sensors
for material characterization that have been developed for past ten years. A decade of …

Three novel refractive index (RI) sensors based on one, two, and three H-shaped cavities
(HCs) and metal–insulator–metal (MIM) waveguides are proposed in this paper. By coupling …

Metamaterials are widely used as sensors in a large range of applications due to their
unusual properties not found in nature. This review's purpose is to focus on recent …

Metamaterial-based devices show properties like negative magnetic permeability and
negative electrical permittivity, which are not found naturally. Due to their extraordinary …

In this paper, a terahertz metamaterial structure with multiple physical features such as EIT-
like resonance, Fano resonance, and terahertz wave absorption, is implemented. The …

A new kind of multi-band metamaterial absorber based on the concentric ring resonators is
engineered to be used in various microwave applications including energy harvesting …

Metamaterials absorber are materials that are not directly found in nature and exhibit
unusual electromagnetic properties. Today, metamaterials have a wide range of …

A digit 8-shaped resonator inspired metamaterial is proposed herein for sensor applications.
The resonator is surrounded by a ground frame and excited by a microstrip feedline. The …

Optical sensors enable quantification of analyte concentrations non-invasively without being
affected from electromagnetic fields. The development of single-mode waveguides (WGs) is …

In this paper, several important applications of a metamaterial absorber (MA) based sensors
such as temperature, pressure, moisture, and density are presented. Since the sensing …
