Simultaneous implementation of antireflection and antitransmission through multipolar interference in plasmonic metasurfaces and applications in optical absorbers and broadband polarizers

open access: yesNanophotonics, 2020
Metasurfaces have been widely used to control beam propagation e.g. transmission, reflection, and absorption on an interface through a thin layer of nanoantennas with the thickness smaller than the wavelength.

NMR relaxation rate in the field-induced octupolar liquid phase of spin-1/2 J1-J2 frustrated chains

open access: yes, 2011
In the spin-1/2 frustrated chain with nearest-neighbor ferromagnetic exchange J1 and next-nearest-neighbor antiferromagnetic exchange J2 under magnetic field, magnetic multipolar-liquid (quadrupolar, octupolar, and hexadecapolar) phases are widely ...

Tech Diplomacy and the Digital International Order: The Case of the EU–U.S. Trade and Technology Council

open access: yesGlobal Policy, EarlyView.
ABSTRACT This article examines the evolving role of the U.S.–EU Trade and Technology Council (TTC) in advancing the EU's digital diplomacy, with a particular focus on its contribution to global digital ordering. Positioned at the intersection of normative engagement and regulatory coordination, the TTC operates as a hybrid mechanism that integrates ...

The role of geometry on dispersive forces

open access: yes, 2005
The role of geometry on dispersive forces is investigated by calculating the energy between different spheroidal particles and planar surfaces, both with arbitrary dielectric properties.

Rebuilding the Ladder? Contemporary Contests Over Industrial Policy

open access: yesGlobal Policy, EarlyView.
ABSTRACT Does the greater embrace of industrial policy globally signal the emergence of a New Washington Consensus? We show that the multiplication of industrial policies, while consequential, signals neither normalisation nor consensus. Rather, industrial policy is increasingly the object of contestation over norms and practices of state ...

Paradigm Shift in the Making? Geopolitical Challenges and Institutional Changes in the International Monetary System: From Neoliberalism to a Pluralist Multipolar Financial Order

open access: yesGlobal Policy, EarlyView.
ABSTRACT This paper examined the critical challenges facing the international monetary system, arguing that they have created conditions for a shift from a neoliberal framework to a pluralist multipolar financial order. Using an interdisciplinary approach that blends international law and international relations, the paper provides an analysis of the ...

Surface - lattice resonances in 2d arrays of spheres: multipolar interactions and a mode analysis

open access: yes, 2017
We present a multipolar model of surface - lattice resonances (SLRs) in 2d arrays of spheres including the electric dipole, magnetic dipole, and electric quadrupole moments of the spheres.

De‐Dollarization Is a Plausible Outcome of the New Washington Consensus

open access: yesGlobal Policy, EarlyView.
ABSTRACT A trend towards de‐dollarization of the global economy in which the US dollar ceases to be used as the world's reserve currency for international transactions confronts some of the existing structures of international economic law, built upon the rules set out by US‐led organizations like the WTO, the IMF, and the World Bank. This article will

Active control of anapole states by structuring the phase-change alloy Ge2Sb2Te5

open access: yesNature Communications, 2019
High-index dielectric nanoparticles support a great wealth of multipolar responses but active tunability is still elusive. Here, the authors report how structured Ge2Sb2Te5 can support multipolar Mie resonances and demonstrate the spectral shifting ...
