The Full Anisotropic Adaptive Fourier Modal Method and its Application to Periodic and Aperiodic Photonic Nanostructures

The thesis introduces the Fourier Modal Method as simulation tool for periodic photonic nanostructures, and extends the method towards the simulation of aperiodic structures using real and complex coordinate transformations. As exemplary cases, the method is applied for the characterization of a woodpile photonic crystal with the first complete photonic bandgap in the visible spectrum, and to the transmission properties of a long period fiber grating

The Einstein Toolkit: A Community Computational Infrastructure for Relativistic Astrophysics

We describe the Einstein Toolkit, a community-driven, freely accessible computational infrastructure intended for use in numerical relativity, relativistic astrophysics, and other applications. The Toolkit, developed by a collaboration involving researchers from multiple institutions around the world, combines a core set of components needed to simulate astrophysical objects such as black holes, compact objects, and collapsing stars, as well as a full suite of analysis tools. The Einstein Toolkit is currently based on the Cactus Framework for high-performance computing and the Carpet adaptive mesh refinement driver. It implements spacetime evolution via the BSSN evolution system and general-relativistic hydrodynamics in a finite-volume discretization. The toolkit is under continuous development and contains many new code components that have been publicly released for the first time and are described in this article. We discuss the motivation behind the release of the toolkit, the philosophy underlying its development, and the goals of the project. A summary of the implemented numerical techniques is included, as are results of numerical test covering a variety of sample astrophysical problems.Comment: 62 pages, 20 figure

Entry in International Encyclopedia of Ethics BOOK DESCRIPTION: Unmatched in scholarship and scope, the International Encyclopedia of Ethics is the most comprehensive and authoritative ethics resource of its kind. Available online or as an eleven-volume print set, the Encyclopedia espouses a broad vision of ethics that creates links to many other disciplines, including medicine, technology studies, computer science, business, religion, and law. Entries range in size from shorter definitions and biographies to extended treatments of major topics, and have been blind-reviewed by both the editorial team and an independent review board to ensure exceptional balance and accuracy throughout. Building on its established strengths, the second edition of the Encyclopedia covers topics, movements, arguments, and figures in normative ethics, metaethics, and applied ethics, containing over 850 fully-cross-referenced A-Z entries which emphasize the richness and diversity of the field. New to this edition are more than 300 original and updated entries which add coverage of contemporary topics including voting ethics, artificial intelligence, moral uncertainty, police bias, narcissism, structural injustice, bullying, biopolitics, legal moralism, and intellectual virtue. In its state-of-the-art electronic form, each entry is hyperlinked to other entries and to electronic editions of the renowned Blackwell Companions and Guides ¯ in all, more than 1,500 scholarly articles. The electronic version will continue to receive annual updates, continuing the legacy of the International Encyclopedia of Ethics as the preferred resource for research-active scholars, students, and general readers wanting to engage with ethics in their professional lives
