Grupo de Aplicaciones de las Microondas (GAM)

Descripción	El grupo de aplicaciones de Microondas (GAM) centra su actividad investigadora en el Desarrollo de técnicas de análisis y diseño de componentes pasivos para aplicaciones de alta frecuencia (microondas y ondas milimétricas), tales como filtros, redes de adaptación, multiplexores, conmutadores, sondas y transiciones. Dichos componentes pasivos se implementan en diversas tecnologías: coaxial, guía de ondas, planar e híbrida (guías integradas en substrato dieléctrico, SIW), así como empleando materiales conductores, dieléctricoss, estructuras periódicas (EBGs) y elementos de sintonía (varactores, sistemas micro-eléctricos-mecánicos como MEMs). El GAM aplica sus métodos de análisis y síntesis al diseño eficiente de los citados componentes a emplear en muy diversos sistemas de comunicaciones, con especial énfasis en el ámbito espacial (cargas útiles de satélite y estaciones terrenas), pero también en comunicaciones móviles, inalámbricas, sistemas RADAR y aplicaciones de defensa. El grupo también se ocupa del diseño y empleo de plataformas espaciales de reducido tamaño (pico y nano-satélites) para misiones científicos, tecnológicas y de sostenibilidad; así como del desarrollo e implantación de sistemas de comunicación por satélite para aplicaciones de teledetección (procesado de imagen de microondas, infrarrojo y visible) y radionavegación (sistema Galileo). La actividad del grupo comienza en 1997, estando integrado actualmente por 15 personas entre investigadores y personal de apoyo. Adicionalmente, existe una fluida colaboración con otras universidades tanto nacionales ( Universitat de València, Universidad Politécnica de Cartagena, Universidad Miguel Hernández de Elche, Universidad de Alicante, Universidad Politècnica de Madrid, Universidad Autónoma de Barcelona, Universidad Pública de Navarra y Universidad de Sevilla ) como internacionales ( University of Pavia y University of Perugia en Italia, University of Brest y University of Limoges en Francia, University of Maryland en USA, University of Waterloo en Canadá). Destacan las colaboraciones con importantes empresas del sector Espacio como Thales Alenia Espacio, RYMSA, EADS-CASA, COM DEV, TESAT y Aurora Software and Testing (spin-off del grupo de investigación) entre otras, así como la estrecha relación que se mantiene con la Agencia Espacial Europea (ESA) y el Consorcio Espacial Valenciano (VSC).
