In this study, a novel metamaterial topology, called M-band nested U-ring resonator (M-NURR), is proposed to provide multiple band operation with an electrically small and geometrically simple unit cell design. The M-NURR unit cell has M-nested and unconnected U-shaped metal rings printed on a dielectric substrate where each ring is primarily associated with a distinct LC type resonance frequency where L and C stand for inductance and capacitance, respectively. Therefore this M-NURR topology has the novel property that each of these resonance frequencies can be controlled almost independently by adjusting the arm length of the associated U-ring. In this study, three different M-NURR structures (for M = 1, 2, 3) are designed, fabricated and characterised both numerically and experimentally with very good agreement. The suggested sub-wavelength M-NURR metamaterial topology is anticipated to be useful in the design of miniaturised multi-band mobile communication devices as it makes the fine tuning of operation frequencies possible by a simple parametric adjustment.

Triangular-Shaped Single-Loop Resonator: A Triple-Band Metamaterial With MNG and ENG Regions in S/C Bands
Yurduseven, Ozan; Yilmaz, Asim Egemen; Sayan, Gönül (Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01)
A new metamaterial topology, called triangular-shaped single-loop resonator (SLR), is introduced with two distinct mu-negative (MNG) regions and one epsilon-negative (ENG) region over the S/C frequency bands. Transmission and reflection characteristics of the suggested subwavelength resonator are analyzed using full-wave electromagnetic solvers, Ansoft HFSS and CST Microwave Studio (MWS), to demonstrate the presence of four closely located resonance frequencies within the 3.3-5.1 GHz range. Effective permit...
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...
Hybrid connection of RF MEMS and SMT components in an impedance tuner
Unlu, Mehmet; Topalli, Kagan; Atasoy, Halil Ibrahim; Demir, Şimşek; Aydın Çivi, Hatice Özlem; Akın, Tayfun (Elsevier BV, 2010-01-01)
This paper presents a systematic construction of a model for a hybrid connected RF MEMS and SMT components in a reconfigurable impedance tuner. The double stub hybrid impedance tuner which employs a high number of MEMS switches is selected to demonstrate the feasibility of the connections. In the hybrid tuner, MEMS switches are actuated with DC bias signals, where SMT resistors de-couple RF from the DC lines. The hybrid tuner is realized in two steps, where the MEMS impedance tuner is fabricated on a glass ...
Singularity Cancellation for Accurate MoM Analysis of Periodic Planar Structures in Layered Media
Adanir, Suleyman; Alatan, Lale (Institute of Electrical and Electronics Engineers (IEEE), 2020-08-01)
One of the singularity cancellation schemes proposed in the literature is applied to calculate singular integrals arising in the method of moments (MoM) analysis of 2-D periodic planar structures in multilayered media. Discrete complex image method is utilized for the accurate approximation of Green's function which also makes possible the application of the Ewald transformation for the efficient computation of the series associated with the periodic structure. This approximation and transformation modifies...
Metamaterial absorber-based sensor embedded into X-band waveguide
SABAH, CUMALİ; TURKMEN-KUCUKSARİ, OZNUR; Sayan, Gönül (Institution of Engineering and Technology (IET), 2014-07-17)
A novel metamaterial sensor, integrated with an X-band waveguide, is proposed for high-resolution measurements of variations in the dielectric constant and/or the thickness of a superstrate layer that covers a pair of absorber unit cells. Variations in superstrate parameters are potentially caused by physical, chemical or biological factors, and can be detected by measuring the corresponding shifts in the resonance frequency of the metamaterial sensor. It is estimated by simulation results that resolution l...
