  • Broadside coupled split ring resonator based multiband monopole patch antenna for wireless communication applications 
    Kizhakooden, Joe; Jose, Jovia; Paul, Nees; Chakyar, Sreedevi P; Sebastian, Anju; Simon, Sikha K; Umadevi, KS; Bindu, C; Andrews, Jolly; Joseph, VP (American Institute of Physics Inc., 2019-10-29)
    The present work reports the development of a multiband monopole patch antenna by utilizing Broadside Coupled Split Ring Resonator (BCSRR) units. This antenna makes use of the resonant property of metamaterial BCSRR units ...
  • Enhancing the resolution in imaging using folded metamaterial split ring resonator structure at microwave frequencies 
    Bindu, C; Chakyar, Sreedevi P; Sebastian, Anju; Simon, Sikha K; Jose, Jovia; Paul, Nees; Umadevi, KS; Kizhakooden, Joe; Andrews, Jolly; Joseph, VP (American Institute of Physics Inc., 2019-10-29)
    A novel and better resolution topology for reducing the sensing area of conventional Split Ring Resonator (SRR) metamaterial structure is proposed. The conventional planar SRR structure is fabricated on a thin flexible ...
  • Humidity Sensitive Flexible Microwave Absorbing Sheet Using Polyaniline–Polytetrafluoroethylene Composite 
    Paul, Nees; Chakyar, Sreedevi P; Umadevi, KS; Sikha, Simon K; Kizhakooden, Joe; Andrews, Jolly; Joseph, VP (Springer, 2018-06-22)
    Pelletized or powdered polyaniline composite, a potential candidate for microwave absorbers, was synthesized in the sheet form for the first time, and its absorption characteristics along with structural, electrical and ...
  • Microwave absorption properties of flexible zinc oxide sheet 
    Paul, Nees; Jimmy, Janet; Chakyar, Sreedevi P; Simon, Sikha K; Kizhakooden, Joe; Bindu, C; Sebastian, Anju; Umadevi, KS; Jose, Jovia; Andrews, Jolly; Joseph, VP (American Institute of Physics Inc., 2019-10-29)
    This paper presents the fabrication and microwave absorption properties of low-cost flexible light-weight zinc oxide (ZnO) sheet. The elastomers, films and foams used as microwave absorbers are made of lossy materials ...
  • Scattering from artificial plasma cylinder using nonstandard FDTD 
    Jose, Jovia; Simo, Sikha K; Sebastian, Anju; Chakyar, Sreedevi P; Kizhakooden, Joe; Paul, Nees; Bindu, C; Umadevi, KS; Andrews, Jolly; Joseph, VP (American Institute of Physics Inc., 2019-10-29)
    This paper implements Nonstandard Finite Difference Time Domain (NS-FDTD) method to analyses the scattering effect of electromagnetic wave by an artificial plasma cylinder. This NS-FDTD which requires less iteration time ...
