of plasmonic -based photovoltaic cells. This technique is quite useful for near - field and far- field analysis which is direly needed to understand the associate phenomenon. The impact of Au nano-grating on light ...
(MgF2). A characteristic narrow band filtering of the MIMstructure at visible region might cause a confinement of intense surface plasmon polaritons (SPPs) at specificmonochromatic frequency inside ...
graphene sheet to lift the forward/backward degeneracy of the surface plasmon - polariton dispersion, creating modes with different propagation properties parallel and antiparallel to the current. We show ...
oscillation of surface electrons around metal nanoparticles (NPs), can lead to field enhancement in the near ‐ field zone of metal NPs. The LSPR frequency strongly depends on the size, geometry, composition ...
grooves with periods of 250-350 nanometers,and groove depths around 500 nanometers. The surfaces can be designed such that practically all incident light withelectric field perpendicular to the groove ...
by two opposite meta- surfaces . The symmetry properties of the near - field acoustic spin angular momenta are revealed by directly measuring local vectorial fields . Our findings advance the understanding ...
electric fields [14]. These self-sustained modes are the so-called surface phonon polaritons (SPhP) [2] and they will be further discussed in this work. More interestingly, the shape of the nanoscale ...
surface plasmon (LSP) modes. Because of the unique capability of sub-wavelength light confinement near metallic surfaces , LSP-induced morphology-tunable light absorption , as well as scalable fabrication ...
hyperbolic phonon polaritons in anisotropic hBN [6], etc. The delocalization associated with vibrational EELS has also been exploited to probe materials and material surfaces with much lower degrees of damage ...
Yablonovitch and Sajeev John [1,2], which opened a brand new field with great impacts for manipulating light . A similar concept for acoustics was also proposed in parallel to electromagnetism, known as phononic ...
