Synthesis of second‐order wide‐passband frequency selective surface using double‐periodic structures
Publikováno v:
IET Microwaves, Antennas & Propagation, Vol 13, Iss 3, Pp 373-379 (2019)
A new second‐order wide‐bandpass frequency‐selective surface (FSS) composed of a two‐dimensional periodic array cascading aperture‐type FSS and strip‐type FSS with different periods is proposed and investigated. The cascading structure of

Acoustic impedance is typically measured using an impedance tube, which requires a material sample physically fitted to the tube. However, the impedance can vary greatly between the material mounted in the tube and the material located in a real envi

International audience; Abstract-In this article, the Modal Expansion Theory is applied to 2D metamaterial cylindrical waveguides. A new code to compute the surface impedances with 2D Finite Element Method is put forward. The surface impedances d

12th European Conference on Antennas and Propagation (EuCAP 2018).
In this talk we show how to break the angular symmetry of electromagnetic response of thin absorbers. Based on our recent results on multichannel metasurfaces, we propose a new concept of asymmetric absorbers in which the absorption coefficient for w

A new leaky-wave antenna (LWA) for continuous beam scanning and broadside radiation is presented. The fabricated and measured planar antenna is fed by surface waves (SWs) and defined by a periodic arrangement of width-modulated microstrip lines for l

A planar periodic structure obtained by 2D repetition of a unit cell consisting of a width-modulated microstrip line is considered. The variation of the modulation parameters in different regions of the surface can be exploited to locally control the
