Graphene is an sp(2) hybridized allotrope of carbon with a honeycomb lattice structure that has many applications in biomedicine owing to its unique physico-chemical properties. Graphene has attracted much interest from scientists for its biomedical potential, including in drug/gene delivery, fluorescent labeling of target analytes, tissue engineering, regenerative medicine and MRI contrast enhancement. However, there are very limited data available concerning the toxicity of graphene, and effor...

Abstract This paper presents a technique of using magnetic metamaterial as a broadband non-resonant artificial high dielectric substrate for achieving enhanced radiation performance in the microwave region. The selected metamaterial (MTM) is the basic single split-ring resonator (SRR) printed on a bare dielectric substrate of permittivity 3.8. When it is electrically excited by a plane wave, a high permittivity of 25 for the frequency range of 0.5GHz to 3.1GHz is achieved. The application of the...

The physical existence of microwave toroidal dipole in a dogbone metallic inclusion-based miniaturized cloaking structure is verified in this paper. The excitation of toroidal dipole moments on the studied composite is verified using multipole scattering formalism. The presence of the toroidal Fano resonance significantly enhances resonant forward scattering from the structure for normal incidence. Multipolar contribution from the electric, magnetic and toroidal moments significantly enhances th...

Black phosphorus (BP) has come into sight as a hopeful two dimensional (2D) material from its time of invention in 2014 through flourishing exfoliation method. Devices possessing nonspecific properties in at least one dimension are generally considered as nanodevices. The far reaching attention on BP based nanodevices came from its unique structural, compositional and functional features. Researchers have focused on 2D structures of BP because of the electron distribution and wide band gap pecul...

A lossy dielectric with an appropriate magnetic property is one of the requirements of a stealth material. The thickness of the absorber and the corresponding bandwidth of absorption are also other deciding factors that determine the choice of the material as microwave absorbers. A stable emulsion, which is lossy as well as magnetic, is promising, since it can be coated on surfaces with required thickness in the desired band. A magnetic nanofluidic emulsion serves the purpose. A microwave absorb...

Magnetic nanofluids can be prepared by dispersing surfacted nanoparticles in an appropriate carrier medium. The microwave absorbing properties of a magnetic nanofluid based on barium hexaferrite (BAF) is promising since BAF is a good microwave absorber. Surfacted BAF particles prepared by Pulsed Laser Ablation in Liquid (PLAL) overcome agglomeration and are stable under normal conditions. The evaluation of parameters namely e′, e″, μ′ and μ″ (real and imaginary parts of permittivity and permeabi...

The practical demonstration of invisibility cloaking has attracted the attention of electromagnetic research community over the decade. The invention of metamaterials has boosted the research on electromagnetic cloaking due their exotic material parameters under plane wave incidence. In this paper, we are proposing the experimental realization of cylindrical cloaking scheme using the dogbone metamaterial by efficiently routing the incident electromagnetic fields around the target metal obstacle ...
