The surface impedance of London superconductors with twodimensional rectangular grooves of infinite length imitating surface roughness is calculated. Dependences of the effective surface impedance and penetration depth on roughness size are obtained for an arbitrary magnetic field direction. Tempera
## Abstract A methodology is presented for the design synthesis of metamaterials that act as thin multifrequency artificial magnetic conductors. These structures are realized by placing a frequencyβselective surface above a conventional prefect electric conductor, separated by a thin dielectric lay
## Abstract In this article, an ultrathin Radar Absorbing Material (RAM) based on highβimpedance surfaces (HIS) has been investigated. Simple analytical formulas for the input impedance of HIS RAM are present and the equivalent model of lumped resistor is given to achieve better absorbing performan
