In this paper, a double V-shaped metasurface that can efficiently convert linear polarizations of electromagnetic (EM) waves in wideband is proposed. Based on the electric and magnetic resonant features of a single V-shaped particle, four EM resonances are generated in a V-shaped pair, leading to significant bandwidth expansion of cross-polarized reflections. The simulation results show that the proposed...
Photonic crystal (PC) with a photonic band gap (PBG) has attracted much attention since the initial predictions of Yablonovitch and John. This active research area has been extended to frequency-dependent metallic-dielectric PC (MDPC) theoretically and experimentally in Keskinen, M.J., et al, (2000). In this paper, the PBG properties are investigated by transform matrix method when disorder is introduced...
