Plasmonic waveguides with an insulator core sandwiched between hyperbolic
metamaterials (HMMs) claddings, ie HIH waveguide, are investigated for achieving wide …

This study introduces a biosensor utilizing photonic crystal fiber (PCF) technology to detect
breast cancer biomarkers. The biosensor features a unique flower core composed of square …

This paper analyzes a multi-layered bowtie nano-antenna, consisting of alternate layers of
silica (SiO 2) and gold (Au). We show that the multi-layered structure can produce six times …

We theoretically investigate several types of plasmonic slot waveguides for enhancing the
detected signal in Raman spectroscopy, which is a consequence of electric field and Purcell …

Nano-antennas are the optical equivalent of antennas that are used to transmit and receive
information at radio frequencies. These antennas have been used in different applications in …

The performance of the composite metal/dielectric multilayered L-shaped nanoantennas for
strong electric field enhancement has been investigated. The bonding and antibonding …

Hyperbolic metamaterials have been demonstrated to have special potential in their linear
response, but the extent of their non-linear response has not been extensively modeled or …

In this paper, composite nanoantenna arrays are simulative designed for energy harvesting
in visible range. The composite nanoantenna on SiO 2 substrate consists of staircase bowtie …

We theoretically investigate the enhancement of the evanescent waves near the surface of a
prism coated with several layers of metals, graphene, and double negative materials. The …
