    The RWG-discretization in Method of Moments (MoM) of the Magnetic-Field and Electric-Field Integral Equations (MFIE, EFIE) show evident discrepancy in the computed RCS, especially for small objects with edges and corners. ...
  • Volumetric testing with wedges for a nonconforming discretization of the Electric-Field Integral Equation 

    Úbeda Farré, Eduard; Rius Casals, Juan Manuel; Heldring, Alexander (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    The discretization in Method of Moments (MoM) of the Electric-Field Integral Equation (EFIE) is traditionally carried out with divergence-conforming sets of basis functions, like the RWG set. This enforces the normal ...
  • RF monitoring of commercial vascular stents with dipole scattering resonances 

    Arauz Garofalo, Gianluca; López Domínguez, Víctor; Hernández Ferras, Joan Manel; Rodríguez Leor, Oriol; Bayés Genis, Antoni; Rius Casals, Juan Manuel; O'Callaghan Castellà, Juan Manuel; García Santiago, Antoni; Tejada Palacios, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
