    Descripció del contingut i pla d'activitats:
    Se pretende evaluar las herramientas de cosimulación Multiphysics para la simulación electrotérmica de estructuras resonantes y filtros para aplicaciones espaciales.
    Una vez decidida la herramienta más adecuada se realizarán simulaciones de resonadores y filtros ya fabricados y medidos a diferentes temperaturas para verificar la eficacia del simulador.

     
    Overview (resum en anglès):
    In this study, we evaluate a multiphysics cosimulation tool for electrothermal simulation of resonant structures and filters for space applications.

    To perform these simulations, we decided to choose, as the main tool for this task, the Comsol Multiphysics software, in its version 4.2. This simulator incorporates a wide range of possibilities for different types of physical studies. In addition, it allows us to perform whether simple analysis with a single physical element or much more complicated analysis, which include the study of different processes closely related.

    Using Comsol, we performed simulations of resonators with different characteristics, by changing the size of the central post of the cavity, or the length of the conductor core of the coaxial input-output connectors. We study the electromagnetic behavior of these resonators, how it varies with changes of the temperature and the structural deformation due to these changes.

    We compare the results of the Comsol electromagnetic simulations with simulations of the same structure using HFSS as reference software.

    Finally, we analyze the behavior of the whole filter, incorporating the results of the electro-thermal analysis of a resonator. This analysis is done ADS, another circuit simulator, and we compare these results with a practical study carried out in a laboratory of the European Space Agency.
