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.

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...

This paper discusses the application of Castigliano's Theorem to a half circular beam intended for use as a shaped, tunable, passively compliant robot leg. We present closed-form equations characterizing the deflection behavior of the beam (whose compliance properties vary along the leg) under appropriate loads. We compare the accuracy of this analytical representation to that of a Pseudo Rigid Body (PRB) approximation in predicting the data obtained by measuring the deflection of a physical half-circular b...
Design of a Test Setup for Measuring Dynamic Stiffness of Vibration Isolators
Uz, Canan; Özgen, Gökhan Osman; Ciğeroğlu, Ender (2014-01-01)
In this paper, design efforts to develop a custom test setup for measuring dynamic stiffness of vibration isolators are presented. The setup is designed to conduct dynamic stiffness measurements for various static preload values and over a certain (target) frequency range. Direct Method has been selected among the methods defined by standards found in the literature. In order to investigate the effect of basic design parameters of the test setup on its overall performance, an equivalent eight degree of free...
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...
