Plasmon tunability in metallodielectric metamaterials

The dielectric properties of metamaterials consisting of periodically arranged metallic nanoparticles of spherical shape are calculated by rigorously solving Maxwell's equations. Effective dielectric functions are obtained by comparing the reflectivity of planar surfaces limiting these materials with Fresnel's formulas for equivalent homogeneous media, showing mixing and splitting of individual-particle modes due to inter-particle interaction. Detailed results for simple cubic and fcc crystals of aluminum spheres in vacuum, silver spheres in vacuum, and silver spheres in a silicon matrix are presented. The filling fraction of the metal f is shown to determine the position of the plasmon modes of these metamaterials. Significant deviations are observed with respect to Maxwell-Garnett effective medium theory for large f, and multiple plasmons are predicted to exist in contrast to Maxwell-Garnett theory.Comment: 6 pages, 4 figure

Translation of lines of Euripides by Thomas Love Peacock

Translation by Thomas Love Peacock of the last five lines of Euripides\u27 Alcestis. An addendum by \u27R. Garnett\u27 (presumably Richard Garnett) notes this. A pencilled note on the verso suggests that the manuscript was given by Garnett to \u27J. Everson\u27 in 1902.https://scholarworks.umt.edu/whicker/1012/thumbnail.jp

Mean Field Theory for Lossy Nonlinear Composites

The mean-field theory for lossy nonlinear composites, described by complex and field-dependent dielectric functions, is presented. By using the spectral representation of linear composites with identical microstructure, we develop self-consistent equations for the effective response. We examine two types of microstructure, namely, the Maxwell-Garnett approximation and the effective medium approximation to illustrate the theory.Comment: 11 pages, LaTeX format, 2 figures, accepted for publication by Solid State Communications 18 November 199

The autonomous life: a pure social view

In this paper I propose and develop a social account of global autonomy. On this view, a person is autonomous simply to the extent to which it is difficult for others to subject her to their wills. I argue that many properties commonly thought necessary for autonomy are in fact properties that tend to increase an agent’s immunity to such interpersonal subjection, and that the proposed account is therefore capable of providing theoretical unity to many of the otherwise heterogeneous requirements of autonomy familiar from recent discussions. Specifically, I discuss three such requirements: (i) possession of legally protected status, (ii) a sense of one’s own self- worth, and (iii) a capacity for critical reflection. I argue that the proposed account is not only theoretically satisfying but also yields a rich and attractive conception of autonomy
