Acoustic wave filters for enhanced performance
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Comunicació de congrés
Accés restringit per política de l'editorialThis paper presents a novel filter configuration based on acoustic wave resonators that allows to obtain filter responses unachievable with the well established ladder configuration, such as arbitrary position of transmission ... -
Acoustic wave transversal filter for 5G N77 band
(Institute of Electrical and Electronics Engineers (IEEE), 2021-10-01)
Article
Accés obertThis work presents the complete synthesis procedure and circuit transformations needed to go from the characteristic polynomials to the transversal network formed by electroacoustic resonators. This filter topology allows ... -

Acoustical impact of roads on medium-sized mediterranean coastal towns
(1996-01)
Article
Accés restringit per política de l'editorialIn the littoral region near Barcelona, roads belonging to the national network go through towns. Among the problems that this situation causes on the urban quality of ltfe is a high degree of noise pollution. By-pass roads ... -
Acoustically penetrable sonic crystals based on fluid-like scatterers
(2015-01-21)
Article
Accés obertWe propose a periodic structure that behaves as a fluid-fluid composite for sound waves, where the building blocks are clusters of rigid scatterers. Such building-blocks are penetrable for acoustic waves, and their properties ... -
Acoustics in water: synergies with marine biology
