    Hybrid Technique Plus Fast Frequency Sweep for the Efficient and Accurate Analysis of Substrate Integrated Waveguide Devices 
    Belenguer Martínez, Ángel; Esteban González, Héctor; Díaz Caballero, Elena; Bachiller Martin, Maria Carmen; Cascón López, Joaquín; Boria Esbert, Vicente Enrique (Institute of Electrical and Electronics Engineers (IEEE), 2011-03)
    In this paper, we adapt a novel mode-matching and method-of-moments hybrid technique to efficiently analyze substrate integrated waveguide (SIW) based devices. The hybrid technique is formulated in terms of a single ...

    Optimized ultrasonic attenuation measures for non-homogeneous materials 
    Genovés Gómez, Vicente; Gosálbez Castillo, Jorge; Carrión García, Alicia; Miralles Ricós, Ramón; Paya Bernabeu, Jorge Juan (Elsevier, 2016-02)
    In this paper the study of frequency-dependent ultrasonic attenuation in strongly heterogeneous materials is addressed. To determine the attenuation accurately over a wide frequency range, it is necessary to have suitable ...

    Ultrasonic signal modality: A novel approach for concrete damage evaluation 
    Carrión García, Alicia; Genovés, V.; Gosálbez Castillo, Jorge; Miralles Ricós, Ramón; Paya Bernabeu, Jorge Juan (Elsevier, 2017)
    [EN] In this paper, a new approach for characterizing material damage, using ultrasonic waves, is proposed. Two concrete series with two types of cement with different C3A content and similar mechanical properties ...
