Descripción del proyecto
MILLIMETER WAVE (MMW) TECHNOLOGY IS AN EMERGING FIELD OF RESEARCH WITH A WIDE RANGE OF APPLICATIONS: WIRELESS PERSONAL AREA NETWORKS, HIGH DATA RATE TRANSMISSION, IMAGING FOR SECURITY SCREENING, NON-DESTRUCTIVE EVALUATION,GEOLOGICAL EXPLORATIONS, REMOTE SENSING OF VEGETATION AND SOIL CONDITIONS, MEDICAL DIAGNOSIS, ETC,, THE DESIGN OF EFFICIENT ANTENNA SYSTEMS FOR THIS TECHNOLOGY IS A KEY POINT FOR ITS PRACTICAL APPLICATION,THE COMPLEXITY IN TERMS OF GEOMETRY AND MATERIAL PROPERTIES OF MMW ANTENNAS, CANNOT BE HANDLED WITHOUT THE AID OF COMPUTER SIMULATORS, ALTHOUGH POWERFUL PACKAGES ARE COMMERCIALLY AVAILABLE, THEIR GENERAL-PURPOSE NATURE IS NOTSUITABLE TO DEAL WITH MANY OF THE CHALLENGES POSED IN THE MMW RANGE: MATERIAL DISPERSION, GEOMETRICAL INVOLVEMENT, ETC,, FOR THIS REASON, TAILORED COMPUTATIONAL TOOLS NEED TO BE DEVELOPED, DESIRABLE QUALITIES OF THESE TOOLSSHOULD BE:1, FORMULATION IN TIME DOMAIN TO HANDLE MMW ULTRAWIDEBAND SYSTEMS,2, ACCURATE MODELING OF THE PROBLEM GEOMETRY AS A WHOLE (ANTENNA AND PACKAGING),3, INCLUSION OF REALISTIC MODELS OF MATERIALS/METAMATERIALS/ELECTROMAGNETIC BANDGAP STRUCTURES IN THE MMW RANGE, OF GENERAL USE IN ANTENNA TECHNOLOGY,4, CAPABILITY OF EFFICIENT OPTIMIZATION OF THE ANTENNA PARAMETERS,5, FAST AND COMPUTATIONALLY AFFORDABLE IN MODERN PARALLEL ARCHITECTURES,OUR SUBPROJECT IS AIMED AT THE DEVELOPMENT OF NEW ALGORITHMS AND HIGH PERFORMANCE COMPUTATIONAL TECHNIQUES TO DESIGN, ANALYZE AND OPTIMIZE MMW ANTENNAS, THESE TECHNIQUES WILL OVERCOME THE CHALLENGES POSED BY THE LEVEL OF COMPLEXITY OF MMW ANTENNAS TO CURRENT NUMERICAL TECHNIQUES, THE NUMERICAL TECHNIQUES DEVELOPED IN THIS WAY WILL BE ALSO OF USE FOR MICROWAVE AND TERAHERTZAPPLICATIONS, WHERE WE PERFORM ACTIVE RESEARCH THROUGH SEVERAL PROJECTS,WE CAN SUMMARIZE THE OBJECTIVES OF THIS PROPOSAL IN THE FOLLOWING ITEMS:1, GENERATE TIME DOMAIN MODELS OF THE DISPERSIVE BEHAVIOR OF MATERIALS/METAMATERIALS/ELECTROMAGNETIC BANDGAP IN THE MMW RANGE,2, GENERATE HIGH-PERFORMANCE FINITE DIFFERENCE TIME DOMAIN (FDTD) CODES UNDER MODERN LOW-COST PARALLEL SHARED/DISTRIBUTED MEMORY ARCHITECTURES,3, EXTEND UNCONDITIONALLY STABLE ALTERNATIVES TO FDTD TO OVERCOME ITS COMPUTATIONAL REQUIREMENTS FOR DENSE GRIDS IN MMW PROBLEMS,4, GENERATE HIGH-PERFORMANCE PARALLEL CODES BASED ON THE NOVEL DISCONTINUOUS GALERKIN FORMULATION OF THE FINITE ELEMENT METHOD IN TIME DOMAIN, USING NODAL/VECTOR FORMULATIONS,5, IMPLEMENT MODELS OF CARBON NANOTUBES AND NANOWIRE ANTENNAS FOR MMW IN TIME DOMAIN INTEGRAL EQUATIONS METHODS SOLVED BY THE METHOD OF MOMENTS,6, DEVELOP EFFICIENT OPTIMIZATION TECHNIQUES (GENETIC ALGORITHMS, PARTICLE SWARM) FOR MMW ANTENNA DESIGN,7, APPLY THESE SIMULATION/OPTIMIZATION TOOLS TO MMW ANTENNA DESIGN AND PROTOTYPING, WITH INDUSTRIAL APPLICATIONS, IN COLLABORATION WITH THE EXPERIMENTAL PARTNERS OF THIS PROPOSAL (UPV/UPC/UPCT) ,THE METHODS BY THEMSELVES, AND THE NOVEL ANTENNA SYSTEMS DESIGNED, CONSTITUTE THE MAIN OUTCOME OF THIS PROJECT, THE PRESENCE OF EPOS IN THIS SUBPROJECT IS NOT MERELY FORMAL, WE ACTUALLY WORK WITH THEM (EADS, INTA, ONERA, CIMNE) UNDER THE PROJECT HIRF-SE, FUNDED BY THE EU-FP7 PROGRAM, TOGETHER WITH 44 EUROPEAN ACADEMIC/INDUSTRIAL PARTNERS, THIS PROJECT HAS A TOTAL COST 26,5 M¿, AND IT DEALS WITH THE CREATION OF ELECTROMAGNETIC SIMULATORS TO BE EMPLOYED IN THE ELECTROMAGNETIC COMPATIBILITY CERTIFICATION PHASE OF MODERN AIRCRAFTS AND ROTORCRAFTS, ANTENAS\BANDA MILIMETRICA\METODOS NUMERICOS\ALGORITMOS DE OPTIMIZACION\COMPUTACION DE ALTO RENDIMIENTO
