Graphene plasmonicPlasmonically induced transparencyMulti-mode transparency windowsWe propose a highly wavelength-tunable multi-mode plasmonically induced transparency (PIT) device based on monolayer graphene and graphene rings for the mid-IR region. The proposed PIT systems explore the near-field coupling ...
Experimental data demonstrate that the transmission modulation depth of the multimode resonance can be realized about 90% under optical power 60 mW, and the off switch of these resonance peaks transmission can be also simultaneously achieved within several picoseconds. Such plasmonic structure is able ...
All of these are based on the single resonance mode in each stub resonator. Recently, Cao et al. used a single multimode stub resonator plasmonic system to realize double PIT30. However, due to the complex inter- action between the multiple modes, the study about multiple multimode stub ...
Resonance is observed at f1=16.95 GHz, f2=24.1 GHz, f3=43.95 GHz, and f4=52.1 GHz, where corresponding length of the unit cell is 0.11×λ1, 0.16×λ2, 0.29×λ3, and 0.34×λ4, respectively. This highlights the unit cell’s capability to support multiple resonances due to its ...
these Pt-GNRs prevent the oxidative damage of healthy cells under the NIR light irradiation. Apart from ROS scavenger ability, these Pt-GNRs have been studied for PTT at the in vitro level50. However, the ROS formation during PTT and its scavenging mechanism by plasmonic nanohybrids are not ye...
These inorganic-based assemblies offer enormous advantages compared to organic-based structures in terms of physicochemical features and morphological attributes, exceptional stability, and unique features of magnetism (iron oxide) and plasmonic resonance (silver and gold) [11], [146], [147]. These ...

Being p-type semiconductors, copper based chalcogenides determine charge trans- port and provide a composition-dependent localized surface plasmon resonance (LSPR) in the near-infrared (NIR) region23–26. In a recent work, Li et al. for the first time demonstrated the possibility of using as-...
To detect the vibrational signature of the GABA molecules, we focus on its distinct absorption peak at 1562 cm−1, resulting from the asymmetric stretching of its carboxylate group. Our platform can efficiently detect the absorption peak of GABA via the first resonance mode of the metasurface...
—3938 K. Bedingfield et al.: Multi-faceted plasmonic nanocavities discussed earlier, this effective mode 'elongation' destroys the central near-field node, with not Ez ≠ 0 for this (2,2) mode at the centre of the nanocavity. This has the remark- able ability to completely dominate the ...
