We present design and computational analysis of multiband metamaterial structures that are fabricated via low-cost inkjet printing. In particular, three-dimensional arrangements of split-ring resonators with different sizes are considered to achieve bandstop characteristics at multiple frequencies. A fast and accurate solver is employed to analyze alternative arrangements, while considering different parameters to obtain strong resonances at desired frequencies. The obtained designs are fabricated in a low-cost inkjet-printing setup, which is based on using conventional printers that are modified and loaded with silver-based inks. Initial results shown in this paper demonstrate the feasibility of low-cost multiband metamaterials. © 2019 EuMCE.

Design, Simulation, and Fabrication of Broadband Inkjet-Printed Log-Periodic Antennas
Dolapci, Turker; Mutlu, Feza; Ergül, Özgür Salih (2017-09-27)
We present design and computational analysis of log-periodic antennas that are fabricated by using low-cost inkjet printing technology. The designed antennas operate in the 1.5-2.5 GHz range and are suitable for diverse applications, including energy harvesting at WiFi and GSM bands. Suitable designs are fabricated by using silver-based inks in standard commercial printers. Despite the challenges in both design and fabrication processes, we demonstrate log-periodic antennas with desired operating properties...
Design and Analysis of Nanoantenna Arrays for Imaging and Sensing Applications at Optical Frequencies
Isiklar, Goktug; Cetin, Isa Can; Algun, Mustafa; Ergül, Özgür Salih (2019-01-01)
We present computational analysis of nanoantenna arrays for imaging and sensing applications at optical frequencies. Arrays of metallic nanoantennas are considered in an accurate simulation environment based on surface integral equations and the multilevel fast multipole algorithm developed for plasmonic structures. Near-zone responses of the designed arrays to nearby nanoparticles are investigated in detail to demonstrate the feasibility of detection. We show that both metallic and dielectric nanoparticles...
Very Low-Cost Inkjet-Printed Metamaterials: Progress and Challenges
İbili, Hande; Ergül, Özgür Salih (2017-09-22)
A very low-cost inkjet printing of three-dimensional metamaterials is studied. By using commercial standard printers and loading them with silver-based inks, we are able to fabricate metamaterial blocks that can operate effectively at the lower frequencies of the X-band. We discuss important challenges in constructing a low-cost inkjet printing setup, as well as the current status on fabricating successful structures without resorting to expensive setups. Despite the challenges, it is shown that relatively ...
Reference-plane-invariant waveguide method for electromagnetic characterization of bi-axial bianisotropic metamaterials
HASAR, UĞUR CEM; Yildiz, Gul; BUTE, MUSA; Muratoğlu, Abdurrahim (2018-11-01)
In this paper, we investigate a reference-plane invariant (RPI) method for electromagnetic property extraction of bi-axial bianisotropic metamaterial (MM) slabs. In order to obtain unique properties, we applied the frequency varying technique in order to determine the location of the slab within its cell. For validation of the proposed method, we first simulated and then measured scattering parameters of a MM slab constructed by split-ring-resonators, next extracted its electromagnetic properties, and final...
