We show that CL only probes the radiative modes, in contrast to EELS, which additionally reveals dark modes. The combination of both techniques on the same particles thus provides complementary information and also demonstrates that although the radiative modes give rise to very similar spatial distributions when probed by EELS or CL, their resonant energies appear to be different. We trace this phenomenon back to plasmon dissipation, which affects in different ways the plasmon signatures probed by these techniques. Our experiments are in agreement with electromagnetic numerical simulations and can be further interpreted within the framework of a quasistatic analytical model. We therefore demonstrate that CL and EELS are closely related to optical scattering and extinction, respectively, with the addition of nanometer spatial resolution.}}, author = {{Losquin, Arthur and Zagonel, Luiz F. and Myroshnychenko, Viktor and Rodríguez-González, Benito and Tencé, Marcel and Scarabelli, Leonardo and Förstner, Jens and Liz-Marzán, Luis M. and García de Abajo, F.

Transfer of optical power carried by planar, semi-guided waves is possible without reflections or radiation losses, and over large vertical distances. This functionality is realized through simple step-like folds of high-contrast dielectric slab waveguides, in combination with oblique wave incidence, and fulfilling a resonance condition. Radiation losses vanish, and polarization conversion is suppressed for TE wave incidence beyond certain critical angles. This can be understood by fundamental arguments resting on a version of Snell’s law. The two 90° corners of a step act as identical partial reflectors in a Fabry–Perot-like resonator setup. By selecting the step height, i.e., the distance between the reflectors, one realizes resonant states with full transmission. Rigorous quasi-analytical simulations for typical silicon/silica parameters demonstrate the functioning. Combinations of several step junctions can lead to other types of optical on-chip connects, e.g., U-turn- or bridge-like configurations.}}, author = {{Hammer, Manfred and Hildebrandt, Andre and Förstner, Jens}}, issn = {{0146-9592}}, journal = {{Optics Letters}}, keywords = {{tet_topic_waveguide}}, number = {{16}}, pages = {{3711--3714}}, publisher = {{The Optical Society}}, title = {{{How planar optical waves can be made to climb dielectric steps}}}, doi = {{10.1364/ol.40.003711}}, volume = {{40}}, year = {{2015}}, } @article{3896, abstract = {{We study the formation of subwavelength solitons in binary metal-dielectric lattices.

The definition of model transformations is usually based on meta-models describing the abstract syntax of languages. While meta-models are thereby able to abstract from uperfluous details of concrete syntax, they often loose structural information inherent in languages, like information on model elements always occurring together in particular shapes. As a consequence, model transformations cannot naturally re-use language structures, thus leading to unnecessary complexity in their development as well as in quality assurance.In this paper, we propose a new approach to model transformation development which allows to simplify the developed transformations and improve their quality via the exploitation of the languages׳ structures. The approach is based on context-free graph grammars and transformations defined by pairing productions of source and target grammars. We show that such transformations have important properties: they terminate and are sound, complete, and deterministic.}}, author = {{Besova, Galina and Steenken, Dominik and Wehrheim, Heike}}, journal = {{Computer Languages, Systems & Structures}}, pages = {{116--138}}, publisher = {{Elsevier}}, title = {{{Grammar-based model transformations: Definition, execution, and quality properties}}}, doi = {{10.1016/j.cl.2015.05.003}}, year = {{2015}}, } @inbook{2921, author = {{Blazy, Olivier and Kakvi, Saqib and Kiltz, Eike and Pan, Jiaxin}}, booktitle = {{Lecture Notes in Computer Science}}, isbn = {{9783662464465}}, issn = {{0302-9743}}, pages = {{256--279}}, publisher = {{Springer Berlin Heidelberg}}, title = {{{Tightly-Secure Signatures from Chameleon Hash Functions}}}, doi = {{10.1007/978-3-662-46447-2_12}}, year = {{2015}}, } @misc{297, author = {{Sosniak, Martin}}, publisher = {{Universität Paderborn}}, title = {{{Evaluation of Pairing Optimization for Embedded Platforms}}}, year = {{2015}}, } @misc{299, author = {{Gerken, Britta}}, publisher = {{Universität Paderborn}}, title = {{{Elektromagnetische Seitenkanalangriffe auf paarungsbasierte Kryptographie}}}, year = {{2015}}, } @misc{301, author = {{Bobolz, Jan}}, publisher = {{Universität Paderborn}}, title = {{{Efficient Verifier-Local Revocation for Anonymous Credentials}}}, year = {{2015}}, } @misc{302, author = {{Stroh, Christian}}, publisher = {{Universität Paderborn}}, title = {{{Efficient Attributes for Pairing-Based Anonymous Credentials}}}, year = {{2015}}, } @phdthesis{304, author = {{Koutsopoulos, Andreas}}, publisher = {{Universität Paderborn}}, title = {{{Dynamics and Efficiency in Topological Self-Stabilization}}}, year = {{2015}}, } @phdthesis{305, author = {{Kniesburges, Sebastian}}, publisher = {{Universität Paderborn}}, title = {{{Distributed Data Structures and the Power of topological Self-Stabilization}}}, year = {{2015}}, } @misc{312, author = {{Schleiter, Patrick}}, publisher = {{Universität Paderborn}}, title = {{{Constructions of Fully Secure Predicate Encryption Schemes}}}, year = {{2015}}, } @article{3120, author = {{Böhl, Florian and Hofheinz, Dennis and Jager, Tibor and Koch, Jessica and Striecks, Christoph}}, journal = {{J.
