FDTD-Based metamaterial (MTM) modeling and simulation
Pekmezci, Ayşegül; Sevgi, Levent (IEEE, 2014-10)Metamaterial (MTM) modeling and simulation using the Finite-Difference Time-Domain (FDTD) method is discussed. The frequency dependence of the permittivity and permeability of the metamaterial is modeled using the Lorentz ... -
Finite difference time domain formulation for epsilon-negative medium using wave equation
Pekmezci, Ayşegül; Topuz, Ercan; Sevgi, Levent (Wiley, 2016-05)A novel approach utilizing one-dimensional (1D) wave equation based finite difference time domain (FDTD) formulations for Lorentz-type Epsilon-Negative (ENG) medium is developed. To demonstrate the validity and accuracy ... -
First and second order mur type ABCs for DNG media
Pekmezci, Ayşegül; Topuz, Ercan; Sevgi, Levent (Applied Computational Electromagnetics Society, 2018)Reflections from boundaries of the FDTD computational domain lead to inaccurate, even unstable codes when dealing with problems involving double negative (DNG) materials. Here, an efficient and simple algorithm is presented ... -
Modal properties of parallel plate waveguide partially loaded with double negative materials
Pekmezci, Ayşegül; Topuz, Ercan (Taylor & Francis, 2019)Properties of eigen-solutions in parallel plate waveguides partially loaded with Lorentz type Double Negative Materials (DNG), modelled by lossless/lossy, identical/non-identical electric, magnetic parameters are presented. ... -
Properties of metamaterial based electromagnetic absorbers and shields
Pekmezci, Ayşegül; Sevgi, Levent (IEEE, 2019)Metamaterials are widely investigated as nominates for absorbers and shields in Electromagnetic Compatibility (EMC) techniques. Due to the dispersive nature of artificially constructed metamaterials, permittivity and/or ... -
Scattering characteristics of FSSs with triangular conducting elements
Pekmezci, Ayşegül; Ege, Tuncay (Springer, 2014-06)In this paper, scattering characteristics of dielectric backed frequency selective surfaces (FSSs) having triangular conducting elements are investigated for both transverse magnetic and transverse electric incident plane ...
