Journal ArticleDOI
Surface-Enhanced Raman Scattering from Silver-Plated Porous Silicon
TL;DR: In this article, the SERS spectra of Rhodamine 6G (R6G) and adenine were obtained using an 18mW, 488-nm laser, and the performance of these analytes was dramatically improved by pretreatment of the silver-plated porous Si samples (Ag−PS) with a 1 mM mineral acid solution.
Journal ArticleDOI
Description and explanation of electromagnetic behaviors in artificial metamaterials based on effective medium theory
TL;DR: A general theory of effective media to set up the relationship between the particle responses and the macroscopic system behaviors for artificial metamaterials composed of periodic resonant structures and proposes a more advanced form of the fitting formulas for the effective electromagnetic parameters of metamMaterials.
Journal ArticleDOI
Hydrodynamic Model for Plasmonics: A Macroscopic Approach to a Microscopic Problem
TL;DR: The basic assumptions and techniques underlying the hydrodynamic model of electron response in metals are presented and it is demonstrated that the model can be easily incorporated into computational models.
Journal ArticleDOI
Design of arbitrarily shaped concentrators based on conformally optical transformation of nonuniform rational B-spline surfaces
Wei Xiang Jiang,Tie Jun Cui,Qiang Cheng,Jessie Yao Chin,Xin Mi Yang,Ruopeng Liu,David R. Smith +6 more
TL;DR: In this paper, the design of arbitrarily shaped electromagnetic (EM) concentrators and their potential applications are studied. But the design is restricted to the case of a rectangular concentrator, which is much more efficient and easier than the existing techniques.
Journal ArticleDOI
Composite Plasmon Resonant Nanowires
TL;DR: In this paper, the polarization-dependent scattering of light from homogeneous and multisegment silver, gold, and nickel nanowires is analyzed using an optical microscope configured for single particle spectroscopy.
