Inkjet-printed frequency-selective structures based on improvedarrangements of U-shaped resonators
Erıs, Ozgur; İbili, Hande; Ergül, Özgür Salih (2019-10-17)
We present design, simulation, and fabrication of thin inkjet-printed frequency-selective structures involving U-shaped resonators. In order to obtain both multiband and polarization-independent operation, resonators are c...
Fast and accurate analysis of three-dimensional structures involving near-zero-index materials
Karaosmanoglu, Bariscan; Koyaz, Yesim; İbili, Hande; Ergül, Özgür Salih (2019-09-01)
We present efficient and accurate frequency-domain analysis of three-dimensional structures involving near-zero-index (NZI) materials with very small permittivity and/or permeability values. Accurate simulations are requir...
Inkjet-printed frequency-selective structures based on improved arrangements of u-shaped resonators
Eris, Ozgur; İbili, Hande; Ergul, Özgür Salih (2019-05-01)
We present design, simulation, and fabrication of thin inkjet-printed frequency-selective structures involving U-shaped resonators. In order to obtain both multiband and polarization-independent operation, resonators are c...
MFIE-Based Formulation Using Double-Layer Modeling for Perfectly Conducting Objects
Guler, Sadri; İbili, Hande; Ergül, Özgür Salih (2019-01-01)
We present resonance-free solutions of scattering problems involving closed conductors using the magnetic field integral equation (MFIE). In the literature, MFIE is often combined with the electric-field integral equation ...
Analysis of Composite Structures Involving Near-Zero-Index Materials
Koyaz, Yesim; İbili, Hande; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2019-01-01)
We consider numerical solutions of electromagnetic problems involving near-zero-index materials with permittivity and/or permeability values close to zero. These types of problems are inherently multiscale due to the large...
Homogenization of Microwave Metamaterial Structures Using Full-Wave Solutions and Genetic Algorithms
İbili, Hande; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2018-11-02)
Metamaterials involve small details that create challenges in their numerical analysis. As commonly practiced, homogenization of such complex structures may simplify and facilitate their numerical solutions. However, homog...
Penetrable Numerical Modeling of Metallic Nanoparticles at Terahertz Frequencies
İbili, Hande; Guler, S.; Karaosmanoglu, B.; Ergül, Özgür Salih (2018-08-04)
Numerical solutions of electromagnetic problems involving nanostructures at terahertz (THz) frequencies are considered. We particularly focus on nanoparticles that are made of typical metals at the lower THz frequencies. E...
Mitigating internal resonances of the magnetic-field integral equation via double-layer modeling
Güler, Sadri; İbili, Hande; Ergül, Özgür Salih (Institution of Engineering and Technology; 2018-04-13)
We present a new method to mitigate internal resonances of the magnetic-field integral equation (MFIE) for closed conductors, without combining this equation with the electric-field integral equation (EFIE) that is commonl...
Demonstration of negative refractive index with low-cost inkjet-printed microwave metamaterials
İbili, Hande; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2018-01-01)
We present low-cost fabrications of inkjet-printed metamaterials that are resonating at microwave frequencies. A very low-cost setup involving commercial desktop printers loaded with silver-based inks is constructed and us...
Design and Fabrication of Low-Cost Inkjet-Printed Metamaterials
İbili, Hande; Karaosmanoglu, Bariscan; 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 a...
