    Dual-band double-negative-index fishnet metamaterial at millimeter-waves 
    Navarro-Cia, M.; García Meca, Carlos; Beruete, M.; Martínez Abietar, Alejandro José; Sorolla, M. (Optical Society of America, 2011)
    [EN] An effective negative refractive index (NRI) is demonstrated and experimentally verified for the first two propagation bands of a fishnet-like metamaterial at millimeter-wave frequencies. The dual-band NRI behavior ...

    Highly-sensitive chemical detection in the infrared regime using plasmonic gold nanocrosses 
    Rodríguez Fortuño, Francisco José; Martínez Marco, Mª Luz; Tomás Navarro, Begoña; Ortuño Molinero, Rubén; Martí Sendra, Javier; Martínez Abietar, Alejandro José; Rodríguez Cantó, Pedro Javier (American Institute of Physics, 2011)
    In this work, we report the design, fabrication, and characterization of gold nanocrosses for chemosensing purposes. The nanocrosses are designed to exhibit a localized surface plasmon resonance which is very sensitive to ...
