Intracellular imaging by exciting multimode resonances in spilt-ring resonators (SRRs) is presented. With advantages such as being label-free, coupler-free, having a tunable spectrum range and intracellular detection length, SRR microscopy is a strong competitor for surface plasmon resonance microscopy ...
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 ...

collective scattering phenomenon within the energy band gaps due to mode coupling between wave-like and particle-like oscillations. The quantum multistream model is further generalized to include virtual streams which is used to calculate the electronic band structure of one-dimensional plasmonic crystals...

As the coupled microwave transmission spectra with multiple resonance peaks are very sensitive to the surface refractive index, this sensor has a significant frequency shift for the paper chip with sweat changes. The sweat volume monitored by this sensor has a linear response in the range of 1.1 ...
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...
Likewise, the near infrared plasmonic absorption feature also enables the NSs to be used for PA imaging and PTT of tumors. Our study clearly demonstrates a unique theranostic nanoplatform that can be used for high performance multi-mode imaging-guided PTT of tumors, which may be extendable for ...
—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 ...
