We propose the design of a multiband absorber based on multi-layered square split ring (MSSR) structure. The multi-layered metamaterial structure is designed to be used in the frequency bands such as WIMAX, WLAN and satellite communication region. The absorption levels of the proposed structure are higher than 90% for all resonance frequencies. In addition, the incident angle and polarization dependence of the multi-layered metamaterial absorber and harvester is also investigated and it is observed that the structure has polarization angle independent frequency response with good absorption characteristics in the entire working frequency band. The energy harvesting ratios of the structure is investigated especially for the resonance frequencies at which the maximum absorption occurs. The energy harvesting potential of the proposed MSSRs is as good as those of the structures given in the literature. Therefore, the suggested design having good absorption, polarization and angle independent characteristics with a wide bandwidth is a potential candidate for future energy harvesting applications in commonly used wireless communication bands, namely WIMAX, WLAN and satellite communication bands.

Energy Harvesting Through Lumped Elements Located on Metamaterial Absorber Particles Gunduz, Ozan T.; Sabah, Cumali (2015-09-09) We propose and examine an enhanced version of a multi-band metamaterial absorber for an energy harvesting application. The numerical results of the multi-band absorption characteristics of no-load conditions are presented and compared with the loading conditions. At most % 50 of the incoming wave energy whose correspondence is 0.25 Watt is converted to real power at the resistive loads at 5.88 GHz by the usage of 2000 ohms loads. In order to evaluate the harvesting efficiency, three different types of effic...
Multi-Band Metamaterial Absorber: Design, Experiment and Physical Interpretation Dincer, F.; KARAASLAN, MUHARREM; ÜNAL, EKİN ANIL; Akgol, O.; Sabah, C. (2014-03-01) This paper presents the design, fabrication, characterization and experimental verification of a perfect Multi-Band Metamaterial (MTM) absorber (MA) based on a simple configuration of a rectangular resonator and strips operating in microwave frequency regime. The proposed multi-band MA provides perfect absorption with TE-incident angle independency. Maximum absorption rate is achieved as 99.43% at 5.19 GHz for simulation and 98.67% at 5.19 GHz for experiment, respectively. The measurement results of the fab...
Tuning the Center of Gravity of 3D Printed Artifacts KELEŞ, Mert; Yaman, Ulaş (Elsevier BV; 2018-06-14) In this study, we propose an Algorithms-Aided Design (AAD) approach to shift the center of gravity of 3D printed artifacts to a predefined location by creating a heterogeneous internal structure utilizing the same type of material. When the conventional design and fabrication pipeline of 3D printers and additive manufacturing machinery is employed, information about the interior of the artifacts is lost during the conversion of the design files to the STL file format. This de facto file standard only stores...
Optimum topological design of geometrically nonlinear single layer lamella domes using harmony search method Çarbaş, Serdar; Saka, Mehmet Polat; Department of Engineering Sciences (2008) Harmony search method based optimum topology design algorithm is presented for single layer lamella domes. The harmony search method is a numerical optimization technique developed recently that imitates the musical performance process which takes place when a musician searches for a better state of harmony. Jazz improvisation seeks to find musically pleasing harmony similar to the optimum design process which seeks to find the optimum solution. The optimum design algorithm developed imposes the behavioral ...
Discrete fiber angle and continuous fiber path optimization in composite structures İnci, Hasan; Kayran, Altan; Department of Aerospace Engineering (2012) Fiber orientation angle stands out as one of the most effective design variables in the design optimization of composite structures. During the manufacturing of the composite structures, one can change the fiber orientation according to the specific design needs and constraints to optimize a pre-determined performance index. Fiber placement machines can place different width tows in curvilinear paths resulting in continuous change of the fiber orientation angle in a layer of the composite structure. By allo...
