Descripción del proyecto THE PRESENT PROJECT CAN BE CONSIDERED A NATURAL CONTINUATION OF THE RESEARCH LINES PREVIOUSLY CONSIDERED IN PROJECTS TEC2007-65376 AND TEC2007-68013-C02-01 BY THE MEMBERS OF THE MICROWAVE GROUP OF THE UNIVERSITY OF SEVILLE, FOLLOWING THE GUIDELINES OF THE MINISTRY, THE MEMBERS OF OUR RESEARCH GROUP HAVE NOW PREFERRED TO JOIN OUR EFFORTS IN A SINGLE ''BIG'' RESEARCH PROJECT, THUS, WE PRETEND TO CONTINUE WITH SEVERAL OF OUR TRADITIONAL GENERAL RESEARCH LINES ALTHOUGH MOVING TO NEW DIRECTIONS THAT INVOLVE NEW CHALLENGING ADVANCED PROBLEMS AND MORE PRACTICALLY-ORIENTED APPLICATIONS, WITH PARTICULAR INTEREST IN THE DESIGN AND APPLICATIONS OF NEW PASSIVE COMPONENTS FOR COMMUNICATION SYSTEMS AND MEDICAL APPLICATIONS, IN THE FRAME OF THE PRESENT PROJECT, OUR INVESTIGATION WILL FOCUS ON TWO GENERAL SUBJECTS: 1) CHARACTERIZATION AND APPLICATIONS OF METAMATERIALS, AND 2) CHALLENGING PROPAGATION/RADIATION PHENOMENA IN PLANAR STRUCTURES, SUBJECT 1) CHARACTERIZATION AND APPLICATIONS OF METAMATERIALS, 1,1) THEORY OF FISHNET METAMATERIALS: EXTENSION OF OUR PREVIOUS ANALYSIS ON THESE STRUCTURES TO THE CASES OF OBLIQUE INCIDENT AND ALSO TO INCLUDE THE EFFECTS OF REALISTIC MATERIALS (LOSSES AND PLASMA BEHAVIOR OF METALS AT OPTICAL FREQUENCIES), THE LIMITS OF THE HOMOGENIZATION PROCEDURES WILL ALSO BE TACKLED, 1,2) HOMOGENIZATION OF RESONANT-RING METAMATERIALS AND ANALYSIS OF SIZE AND EDGE EFFECTS, THE VERY IMPORTANT PRACTICAL ISSUE OF THE BUILDING OF AN ACTUAL 3D METAMATERIAL WILL BE CONSIDERED, IN PARTICULAR, IT WILL BE STUDIED ITS TOPOLOGICAL AND MATERIAL REQUIREMENTS AS WELL AS THE FINITE-SIZE EFFECTS INHERENT TO REALISTIC REALIZATIONS, 1,3) DESIGN OF METAMATERIALS FOR MAGNETIC RESONANCE IMAGING, SINCE ONE OF THE MOST APPARENT APPLICATIONS OF METAMATERIALS TURNS OUT TO BE THE ENHANCING OF ELECTROMAGNETIC IMAGING, WE PRETEND TO CONTINUE OUR PREVIOUS WORK ON THOSE TOPIC TO EXPLORE THE POSSIBILITIES OF THIS EMERGING TECHNOLOGY, PAYING SPECIAL ATTENTION TO ITS PRACTICAL IMPLEMENTATION,SUBJECT 2) CHALLENGING PROPAGATION/RADIATION PHENOMENA IN PLANAR STRUCTURES, 2,1) ANALYSIS AND DESIGN OF PERIODIC STRUCTURES, WE WILL FOCUS OUR INVESTIGATION IN BOTH THE THEORETICAL ASPECTS AND THE PRACTICAL REALIZATION OF ENHANCED PLANAR FREQUENCY-SELECTIVE SURFACES AND LEAKY-WAVE ANTENNAS, ALSO IT WILL BE TREATED THE PLASMONIC ENHANCED TRANSMISSION/REFLECTION PROPERTIES OF PERIODIC SCREENS, 2,2) NOVEL TOPOLOGIES FOR PRINTED FILTERS, WE AIM TO DEVELOP NEW CONFIGURATIONS FOR PRINTED PLANAR NARROW AND UWB FILTERS, DUAL FILTERS AND OTHER PASSIVE DEVICES USING HYBRID MICROSTRIP/CPW STRUCTURES, COMPACT RESONATORS AND 1D PERIODIC CONFIGURATIONS,2,3) HIGH-FREQUENCY CHARACTERIZATION OF DISCONTINUITIES, THE APPEARANCE OF NEW PHENOMENA AT HIGH FREQUENCY (SUCH AS THE EXCITATION OF LEAKY WAVES, RESIDUAL WAVES, AND RADIATION) CAN MODIFY CONSIDERABLY THE BEHAVIOR OF THE DISCONTINUITIES, OUR INVESTIGATION WILL FOCUS ON THESE HIGH-FREQUENCY EFFECTS AND ITS POSSIBLE CHARACTERIZATION VIA SIMPLIFIED CIRCUIT MODELS,2,4) SIGNAL INTEGRITY IN COUPLED PRINTED LINES, WE WILL CONTINUE WITH OUR PREVIOUS WORK ON THIS RELEVANT PRACTICAL ISSUE, IN PARTICULAR WE WILL FOCUS OUR ATTENTION ON THE CROSSTALK EFFECTS BETWEEN NEIGHBOUR LINES IN PRINTED TRANSMISSION STRUCTURES DUE TO THE APPEARANCE OF HIGH-FREQUENCY SPURIOUS PHENOMENA,
