The field of plasmonics has grown dramatically over the past decade and still continues growing towards new directions that are continuously emerging. With the ability to produce highly confined optical fields, the conventional rules for light-matter interactions need to be re-examined,and researchers are venturing into new formulations. We are presenting a project, with the primary objective of extending the scope of applications of exact integral-equation (IE) method of moments (MoM) formulations to the electromagnetic analysis of plasmonic nanostructures and artificial materials(metamaterials) in visible and near-infrared frequency bands.<\/p>\n<p>This new project can be seen as the natural continuation of the previous one in which the most efficient algorithms have been successfully combined with smart parallelizing strategies, resulting in highly efficient and scalable EM codes, having achieved the World Record in computational electromagnetics for several times. Now we confront a new challenge: to extend the use of exact MoM solutions to nanoscience and nanotechnology fields. So we must reformulate the integral equations in order to model plasmonic effects associated with resonant collective oscillations which appear in metals at optical frequencies. This basic objective will enable later application objectives, namely to go deep into the accurate design of optical nanoscale antennas and artificial materials and their applications. Optical antennas will allow the nanoscale control of the direction of photon emission, which will enhance many sensing and detection applications in the optical domain, such as nano-optical microscopy, spectroscopy and light emitting devices, including single-photon sources. Regarding the artificial materials, by removing conventional constraints on realizable properties, attainable in naturally occurring materials, the metamaterial concept enables the possibility of creating artificial media with unusual electromagnetic\/optical properties, such as negative index of refraction, plasmonic behavior, etc.; which enables a wide range of applications in the fields of electromagnetic and optical technologies. We know that the objectives proposed in this project are in the leading edge frontier of science, but the experience in previous projects together with our solid background in electromagnetism constitute the best guarantees for the successful overcoming of the tasks involved in this new challenge, mainly taking into account that they are firmly grounded in classical electrodynamics.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"field field-name-field-proy-objetivos field-type-text-long field-label-above\" style=\"text-align: justify;\">\n<div class=\"field-label\"><strong>Objectives:\u00a0<\/strong><\/div>\n<div class=\"field-items\">\n<div class=\"field-item even\">\n<ul>\n<li>Supercomputing electromagnetic tools for plasmonic materials and metamaterials: The first objective is to extend the scope of applications of the SIE-MoM formulations and latest breakthroughs in fast and parallel integral-equation algorithms to the electromagnetic analysis of plasmonic nanostructures and artificial materials in visible and near-infrared frequency bands. This main objective is divided in the following partial objectives:\n<ul>\n<li>SIE-MoM formulations for plasmonic materials and metamaterials: The basic SIE-MoM formulations will be developed for the solution of problems with multiple plasmonic and metamaterial objects. We will focus on formulations with proved high accuracy and convergence. These formulations will be adapted and further optimized to account for the quite different and non-naturally occurring electromagnetic response of metamaterials and plasmonic media at optical frequencies.<\/li>\n<li>Fast algorithms and parallelization in HPC computers: Efficient fast solving algorithms will be redesigned and adapted to the previous formulations by considering the unusual behavior of waves that might appear in these generalized media. The FMM and MLFMA will be chosen for shared-memory computers. For distributed and mixed memory configurations, the high scalability MLFMA-FFT will be adapted and parallelized, allowing to benefit from the availability of massively parallel supercomputers, with thousands of parallel processors and large amounts of memory.<\/li>\n<\/ul>\n<\/li>\n<li>Engineering nanoscience applications: The other main objective is the application of the implemented advanced techniques to the precise electromagnetic analysis of artificial materials and plasmonic nanostructures. Among the vast number of applications we will focus on those that are most promising, in the leading edge of nanoscience and nanotechnology, and where greater benefits can be taken from the proposed simulation tools. This objective is divided in two partial objectives:\n<ul>\n<li>Plasmonic nano-optical antennas: We will address the precise design of optical nanoscale antennas and array antennas for field enhancement and directional light emission. This will lead to important advances in many applications, from nano-optical microscopy and spectroscopy to quantum-computing. For example, we will attempt to demonstrate the feasibility of complete wireless nano-optical links supported by directive array nanoantennas. For the most challenging and computationally intensive tasks in the scope of this objective, we will count on the support provided by\u00a0<a href=\"http:\/\/www.cesga.es\/\">CESGA<\/a> and <a href=\"\/en\/descripcion-centro\/\">Extremadura Supercomputing Center<\/a>.<\/li>\n<li>Analysis and design of metamaterials: We will apply the SIE-MoM formulations to the solution of homogenized LHM problems. We will mainly focus on control of light applications, including the accurate design of hyperlenses, as well as on the design of electromagnetic selective frequency panels. At a second stage, we will address the detailed design of the microscopic plasmonic subunits to obtain the desired effective macroscopic parameters for artificial materials. This challenging task will require the resolution of extremely large matrix systems, for which we count on the support provided by\u00a0<a href=\"http:\/\/www.cesga.es\/\">CESGA<\/a> and <a href=\"\/en\/descripcion-centro\/\">Extremadura Supercomputing Center<\/a>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"field field-name-field-proy-objetivos-alcanzados field-type-text-long field-label-above\" style=\"text-align: justify;\">\n<div class=\"field-label\"><strong>Objetivos alcanzados:\u00a0<\/strong><\/div>\n<div class=\"field-items\">\n<div class=\"field-item even\">\n<ul>\n<li>Se ha extendido el m\u00e9todo de los momentos basado en formulaci\u00f3n integral superficial al an\u00e1lisis exacto de todo tipo de objetos penetrables arbitrarios en el contexto de las aplicaciones en nanociencia y nanotecnolog\u00eda.<\/li>\n<li>Se han aplicado los \u00faltimos avances en aceleraci\u00f3n espectral a la resoluci\u00f3n r\u00e1pida, precisa y eficiente (bajo coste computacional) de este tipo de problemas.<\/li>\n<li>Utilizando las herramientas de simulaci\u00f3n anteriores y las capacidades de c\u00e1lculo del\u00a0<a href=\"http:\/\/www.cenits.es\/cenits\/lusitania\">supercomputador LUSITANIA<\/a>, del\u00a0<a href=\"http:\/\/www.cenits.es\/cenits\">C\u00e9nitS<\/a>, se est\u00e1 acometiendo con gran \u00e9xito el dise\u00f1o de distintas aplicaciones con gran impacto cient\u00edfico\/tecnol\u00f3gico en el \u00e1mbito de la nanociencia y la nanotecnolog\u00eda:<\/li>\n<li>Dise\u00f1o de nanoantennas plasm\u00f3nicas directivas a frecuencias \u00f3pticas.<\/li>\n<li>Dise\u00f1o de nanoenlaces directivos para comunicaciones intra\/intercircuitales de gran inter\u00e9s para los futuros circuitos integrados \u00f3pticos en escalas nanom\u00e9tricas.<\/li>\n<li>Dise\u00f1o de capas de invisibilidad para la ocultaci\u00f3n de estructuras arbitrarias compuestas por materiales arbitrarios (PECs, diel\u00e9ctricos, plasm\u00f3nicos, metamateriales).<\/li>\n<li>Dise\u00f1o de p\u00f3cimas de invisibilidad para la ocultaci\u00f3n de estructuras penetrables arbitrarias (diel\u00e9ctricos, plasm\u00f3nicos, metamateriales).<\/li>\n<\/ul>\n<p>Todos los avances anteriores est\u00e1n en la frontera de la investigaci\u00f3n en electromagnetismo computacional y presentan un gran inter\u00e9s en el contexto de las actuales y futuras aplicaciones nanotecnol\u00f3gicas.
