    • C0-IPM with generalised periodicity and application to flexoelectricity-based 2D metamaterials 

      Balcells Quintana, Oscar; Codony Gisbert, David; Fernández Méndez, Sonia (2022-05-18)
      Article
      Accés obert
      We propose a methodology to solve high-order PDE boundary value problems with generalised periodicity, in the framework of the C0 interior penalty method. The method is developed for the analysis of flexoelectricity- based ...

    • Computational modeling of flexoelectrity and applications 

      Navarrete Manso, Gabriel (Universitat Politècnica de Catalunya, 2022-10)
      Projecte Final de Màster Oficial
      Accés obert
      In this thesis we focus on computational modelling of flexoelectricity for the design of metamaterials exhibiting apparent piezoelectricity. To do this, we introduce generalized periodicity conditions in an existing finite ...

    • Design of woven meta-materials for electronic textiles for functional applications 

      Zribi, Hanen; Hadj Taieb, Amine; Gil Galí, Ignacio; Fernández García, Raúl; Ardanuy Raso, Mònica (2023)
      Article
      Accés obert
      In this paper, woven wearable metamaterials are developed. For this purpose, several frequency selective surface (FSS) textile absorbers are proposed. The main structure of the FSS consists of a fabric with different patch ...

      Accés restringit per decisió de l'autor
      This project is about the design of a circular polarized microstrip antenna with metamaterial supersubstrate working in the recently European Union Navigation band, Galileo. The metamaterial structure design,which is made ...

    • E-textile metamaterials: stop band pass filter 

      Moradi, Bahareh; Fernández García, Raúl; Gil Galí, Ignacio (Multidisciplinary Digital Publishing Institute, 2021-11-19)
      Article
      Accés obert
      In this paper, the utilization of common fabrics for the manufacturing of e-textile metamaterial is investigated. The proposed design is based on a transmission line loaded with split-ring resonators (SRRs) on a cotton ...

    • Effect of smart textile metamaterials on electromagnetic performance for wireless body area network systems 

      Moradi, Bahareh; Fernández García, Raúl; Gil Galí, Ignacio (2018-09-30)
      Article
      Accés obert
      In this work, the utilization of different textile materials for manufacturing of metamaterial with the aim of controlling the signal propagation in smart textile applications is investigated. The performance of composite ...
