On Multiscale Methods in Petrov-Galerkin formulation [PDF]

open access: yes, 2014
In this work we investigate the advantages of multiscale methods in Petrov-Galerkin (PG) formulation in a general framework. The framework is based on a localized orthogonal decomposition of a high dimensional solution space into a low dimensional ...

A vertex-based finite volume method applied to non-linear material problems in computational solid mechanics [PDF]

open access: yes, 2002
A vertex-based finite volume (FV) method is presented for the computational solution of quasi-static solid mechanics problems involving material non-linearity and infinitesimal strains. The problems are analysed numerically with fully unstructured meshes

The Realization of Multidirectional, Free‐Standing 3D Plasmonic Nanostructures via 3D Nanoprinting: A Case Study of Fractal Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Free‐standing plasmonic gold‐based fractal antennas are fabricated by 3D nanoprinting, employing focused electron beam induced deposition and an optimized purification method to remove carbon while conserving structural fidelity. Simulation and experiment show broadband plasmonic activity, including customizable polarizability, thereby paving the way ...

Convergence of a discontinuous Galerkin multiscale method [PDF]

open access: yes, 2012
A convergence result for a discontinuous Galerkin multiscale method for a second order elliptic problem is presented. We consider a heterogeneous and highly varying diffusion coefficient in $L^\infty(\Omega,\mathbb{R}^{d\times d}_{sym})$ with uniform ...

Tailoring Chiral Gold Nanorods via Single‐Step Seed‐to‐Au(III) Ratio and Unlocking their Potential in Refractive Index Sensing

open access: yesAdvanced Optical Materials, EarlyView.
A single‐step tunable chiral growth of Au NRs with controllable circular dichrosim (CD) response is reported, and the application of narrow CD response for biosensing with superior Figures of Merit (FoM = RIS/linewidth) over conventional extinction‐based approach in sensitivity is demonstrated.
