Focusing surface plasmons via changing the incident angle [PDF]
, 2008 We report a circular metallic aperture with a subwavelength circular slit in the microwave regime, in which we experimentally demonstrate that this aperture can excite and focus surface plasmons.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI
Advanced Functional Materials, EarlyView.Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Mechanism of surface plasmon polarition propagation for nano-optics applications [PDF]
, 2013 In recent times a new emerging research field has become more and more popular in the optics community, which is plasmonics. This discipline studies the surprising optical properties of metals at the nano-scale, which are substantially different from ...

Characteristic energy loss of electrons in Mg with angle resolution
Physics of Complex Systems, 2020 The article discusses electron energy loss of bulk and surface plasmons in solid polycrystalline Mg films. The experimental study of the electrons’ characteristic energy loss is conducted and its results are compared in a wide range of electron incidence

Partially coherent surface plasmon modes [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 Elementary long-range plasmon modes are described assuming an exponential dependence of the refractive index in the neighbourhood of the interface dielectric-metal thin film. The study is performed using coupling mode theory. The interference between two

Advanced Healthcare Materials, EarlyView.We develop a covalent organic framework‐loaded Traditional Chinese Medicine monomer nanodrug delivery system (ISL@bCOF) via boron‐oxygen bonds, a smart response to glucose for delivering AI‐driven isoliquiritigenin (ISL) targeting ZBP1. This dynamic release mechanism, combined with transdermal delivery technology via potent microneedles, can modulate ...

Path entanglement of surface plasmons
New Journal of Physics, 2015 Metals can sustain traveling electromagnetic waves at their surfaces supported by the collective oscillations of their free electrons in unison. Remarkably, classical electromagnetism captures the essential physics of these ‘surface plasma’ waves using ...

Localized surface plasmons of gold nanoparticles
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2022 In this paper, gold nanoparticle far-field and near-field optical responses are studied and simulated numerically. The electromagnetic field was excited by an electric dipole near one end of the nanorod, which is used to model the emission of a quantum ...
