We present multiband nanoantennas that can provide large enhancement factors at multiple frequencies in the optical spectrum. The structures are obtained by opening slits on the conventional bowtie designs. Since frequency/geometry scaling is not valid due to plasmonic properties of metals, two dimensional scans are performed using a rigorous solver based on surface integral equations and method of moments. The results demonstrate the feasibility of nanoantennas with multiband characteristics that can be useful in energy harvesting, bio-sensing, and optical imaging applications.

Investigation of Nanoantenna Geometries for Maximum Field Enhancements at Optical Frequencies Ustun, E.; Eroglu, O.; Gür, Uğur Meriç; Ergül, Özgür Salih (2017-05-25) We present a comparative study of nanoantennas for maximum power enhancements at their feed gaps. Due to frequency-dependent plasmonic properties of metals at optical frequencies, removing the frequency-size relationship used in perfectly conducting models, two-dimensional analysis involving both frequency and geometric scaling is performed to accurately assess the performances of different geometries. Computationally intensive simulations involving thousands of full-wave solutions are carried out by employ...
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...
Computational simulation and realization of three-dimensional metamaterials with various exotic properties İbili, Hande; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2019) In this study, computational analysis and realization of three-dimensional metamaterial structures that induce negative and zero permittivity and/or permeability values in their host environment, as well as plasmonic nanoparticles that are used to design metamaterials at optical frequencies are presented. All these electromagnetic problems are challenging since effective material properties become negative/zero, while numerical solvers are commonly developed for ordinary positive parameters. In real life, t...
Computational analysis of network activity and spatial reach of sharp wave-ripples Canakci, Sadullah; Toy, Muhammed Faruk; Inci, Ahmet Fatih; Liu, Xin; Kuzum, Duygu (Public Library of Science (PLoS), 2017-9-15) Network oscillations of different frequencies, durations and amplitudes are hypothesized to coordinate information processing and transfer across brain areas. Among these oscillations, hippocampal sharp wave-ripple complexes (SPW-Rs) are one of the most prominent. SPW-Rs occurring in the hippocampus are suggested to play essential roles in memory consolidation as well as information transfer to the neocortex. To-date, most of the knowledge about SPW-Rs comes from experimental studies averaging responses fro...
Design of a dual polarized low profile antenna for microwave brain imaging Üçel, Kaan; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-5-9) In this thesis, a low profile, low cost, wide band (0.9-2GHz) dual linearly polarized printed dipole antenna is designed to be used in microwave brain imaging systems. Dual polarization feature offers superior data acquisition through polarization diversity for better image quality. Starting from a simple printed dipole, antenna structure is modified step by step to meet these design requirements. Since a conductive surface in close vicinity of the antenna affects antenna performance, in order to obtain uni...
