A novel metamaterial, which exhibits a wideband double negative behavior in X-band, is proposed, designed, and investigated in this paper. The metamaterial is composed of modified S-shaped split-ring resonators (S-SRR). The periodic structure is designed and simulated using CST MWs. Next, the experiments are carried out, and it is shown that the simulation and the experimental results agree well and the designed structure has a wide bandwidth in X-band. An absorber application of this metamaterial is also provided, and the structure can be used as an absorber with absorption rate of over 80% for the polarization angles between 0 degrees and 40 degrees.

Effects of Substrate Parameters on the Resonance Frequency of Double-sided SRR Structures under Two Different Excitations Ekmekci, E.; Averitt, R. D.; Sayan, Gönül (2010-07-08) In this study, we numerically investigate the effects of substrate parameters (i.e., the thickness and the permittivity) on the resonance frequency of the double-sided SRR (DSRR) structure under two different excitation conditions. This includes either electric or magnetic excitations which are two common techniques to obtain a resonant effective permittivity or permeability, respectively. The numerical calculations are performed using CST Microwave Studio. The numerical results reveal a similar trend in th...
Design and Fabrication of Low-Cost Inkjet-Printed Metamaterials İbili, Hande; Ergül, Özgür Salih (2017-09-27) We consider three-dimensional metamaterials involving split-ring resonators (SRRs) that are produced by using low-cost inkjet printing. Following their three-dimensional computational simulations, sensitivity analysis is applied on SRR arrays in order to evaluate their tolerance to various fabrication errors. We use silver-based inks in standard commercial printers in order to fabricate SRRs and their arrays. Measurements demonstrate the feasibility of fabricating very low-cost three-dimensional metamateria...
A tunable multi-band metamaterial design using micro-split SRR structures EKMEKÇİ, Evren; TOPALLI, Kagan; Akın, Tayfun; Sayan, Gönül (2009-08-31) This paper presents the results of a feasibility study for the design of multi-band tunable metamaterials based on the use of micro-split SRR (MSSRR) structures. In this study, we have designed and constructed a conventional split-ring resonator (SRR) unit cell (type A) and two modified SRR unit cells having the same design parameters except that they contain two (type B) or four (type C) additional micro-splits on the outer square ring, along the arm having the main split. Transmission characteristics of t...
A Novel Dual-band Metamaterial Structure Ekmekci, E.; Turban-Sayan, G. (2009-08-21) In this study, we propose a novel metamaterial structure having magnetic resonances at two different frequencies and hence providing negative effective permeability values over two separate bandwidths. The introduced metamaterial unit cell topology in this paper is made of a single loop of conducting strip printed over a dielectric substrate with a special winding geometry. Transmission and reflection spectra of this unit cell are simulated using the Ansoft's HFSS software to observe its resonance frequenci...
Effects of Array Dimensions on the Resonance Characteristics of SRR Type Metamaterial Arrays with Small Sizes: Simulations and Experiments Ekmekci, E.; Topalli, K.; Akın, Tayfun; Sayan, Gönül (2009-08-21) It has been discussed in various studies that two dimensional periodical arrays of SRRs with large array sizes have wider stop bandwidths and lower transmission magnitudes around their resonance frequencies as compared to the single SRR unit cell. In this paper, effects of array dimensions on the transmission characteristics of SRR arrays are investigated in more detail especially for small sized arrays in a comparative manner. For this purpose, various SRR arrays with small array sizes are fabricated and t...
