Within the frame of a simple, long-wavelength, quasi-static description, we present theoretical characterization optical response metal nanoparticles doped with active gain elements in core-shell (metallic core within an dielectric shell) and nano-shell (active metallic configurations. The common feature these structures is that, adding to system produces increase quality plasmon resonance, whi...

Fano resonance with high Q-factor can greatly enhance the light–matter interaction in all-dielectric metasurface, which is an important condition for developing high-performance micro-/nano-photonics devices. In this paper, we present metasurface structure composed of nanoarrays to investigate properties BIC realization and near-infrared spectral region. Four profiles are generated, two quasi-B...

Microstructured all-optical switching, possessing the unique function of light controlling light, is an important part on-chip ultra-fast optical connectivity network and integrated logic computing chip. switching has attracted extensive research interest, latest great developments which have also yielded progress in nanophotonics, nonlinear optics, communications, etc. The emergence two-dimens...

nowadays, the use of innovative nano-technology in the food industry quality control has significantly increased and it is widely employed in numerous fields such as diagnosis of microbial toxin of foods using nano-biosensors, increasing food shelf-life with the help of nano-clay and nano-silver packaging, as well as changing some of the unpleasant organoleptic properties such as taste, color, ...

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...

Molecular electronics offer an alternative pathway to construct nanoscale circuits in which the critical dimension is naturally associated with molecular sizes. We describe the fabrication and testing of nanoscale molecular-electronic circuits that comprise a molecular monolayer of [2]rotaxanes sandwiched between metal nanowires to form an 8 × 8 crossbar within a 1 μm2 area. The resistance at e...
