Computational design of nanoantennas with improved power enhancement capabilities via shape optimization Işiklar, Göktuǧ; Yazar, Şirin; İbili, Hande; Onay, Gülten; El Ahdab, Zeina; Ergül, Özgür Salih (2023-01-01) Computational design and analyses of nanoantennas obtained via surface shape optimization are presented. Starting with a kernel geometry, free deformations are applied on selected surfaces to reach optimal designs that can...
A novel surface-integral-equation formulation for efficient and accurate electromagnetic analysis of near-zero-index structures İbili, Hande; Ozmu, Utku; Karaosmanoglu, Bariscan; Ergül, Özgür Salih (2022-03-01) We consider accurate and iteratively efficient solutions of electromagnetic problems involving homogenized near-zero-index (NZI) bodies using surface-integral-equation formulations in the frequency domain. NZI structures c...
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.

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...
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 ...
Homogenization of Microwave Metamaterial Structures Using Full-Wave Solutions and Genetic Algorithms İbili, Hande; 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; 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...
