Reflection and transmission properties of a new type of frequency selective surface (FSS) made of zigzag metallic elements placed periodically on a dielectric substrate are investigated theoretically for arbitrary polarisation. The electric field integral equation technique with the subdomain overlapping piecewise sinusoidal basis functions are employed to compute the unknown current coefficients induced on the metallic elements. The zigzag FSS arrays act as a low-pass filter in S-(1-5 GHz), X-(8-12 GHz) and K-u-(12-18 GHz) bands. Owing to multiple resonances the zigzag FSS arrays can be used in multiband frequency applications. Between the resonances there exist transmission windows that allow full energy transfer. By removing the first and third arms, the power reflection coefficient of three-arm zigzag FSS is compared with a freestanding strip FSS, and it is compatible with the measured and calculated results found in the literature.

U-shaped frequency selective surfaces for single- and dual-band applications together with absorber and sensor configurations
Bakir, Mehmet; DELİHACIOĞLU, KEMAL; KARAASLAN, MUHARREM; Dincer, Furkan; Sabah, Cumali (Institution of Engineering and Technology (IET), 2016-02-19)
In this study, the frequency selective surface (FSS), absorbance and sensing applications of new unit cells comprised of single, double and quad U-shaped metallic elements are numerically and experimentally investigated. The numerical results are realised by using finite integration technique-based electromagnetic simulation software, CST Microwave Studio. Experimental results are obtained by means of Agilent N5234A PNA-L vector network analyser. The simulated and measured results of U-shaped FSSs are carri...
Reflection Phase Characterization of Curved High Impedance Surfaces
Durgun, Ahmet Cemal; Birtcher, Craig R. (Institute of Electrical and Electronics Engineers (IEEE), 2013-12-01)
Reflection phase characteristics of cylindrically curved high impedance surfaces (HISs) are examined. Due to the non-periodicity of the problem, full wave solutions can be time consuming. To overcome this problem, an approximate semi-analytical method, which assumes a homogenized model for the curved HIS, is developed. The model parameters can be extracted from the reflection properties of the flat HIS. For the cases where only Floquet currents are excited, the reflection phase diagram of a curved HIS is in...
Circumferential Traveling Wave Slot Array on Cylindrical Substrate Integrated Waveguide (CSIW)
Bayraktar, Omer; Aydın Çivi, Hatice Özlem (Institute of Electrical and Electronics Engineers (IEEE), 2014-07-01)
Traveling wave slot array on cylindrical substrate integrated waveguide (CSIW) is designed, fabricated and measured at K-band. CSIW is formed by wrapping the substrate integrated waveguide (SIW) around the cylinder in the circumferential direction. 16 element longitudinal slot array on the broad wall of single CSIW is designed by the Elliot's design procedure. The spacings between the slot elements are determined to reduce the half power beam width (HPBW) and to obtain good matching at 25 GHz. A 4 x 16 slot...
Triple stub circuit topology as simultaneous insertion phase, amplitude and impedance control circuit for phased array applications
Unlu, M.; Demir, Şimşek; Akın, Tayfun (Institution of Engineering and Technology (IET), 2012-10-23)
This study shows that the well-known triple stub circuit topology can also be used for controlling the insertion phase and amplitude of a given signal simultaneously, as well as preserving its impedance transformation ability. The triple stub circuit topology, which is nothing but an extension of the conventional double stub loaded-line phase shifter, results in one more degree of freedom to its solution when it is solved for its insertion phase. This additional degree of freedom not only brings the impedan...
Single loop resonator: dual-band magnetic metamaterial structure
EKMEKÇİ, EVREN; Sayan, Gönül (Institution of Engineering and Technology (IET), 2010-03-04)
A novel sub-wavelength metamaterial structure, called a single loop resonator, is presented, providing two separate magnetic resonance frequencies in addition to an electric resonance in the microwave region. Transmission and reflection characteristics of the proposed topology are simulated using both Ansoft HFSS software and CST Microwave Studio software for the verification of numerical results. Effective medium parameters of this metamaterial structure are also extracted to demonstrate the presence of tw...
