Characteristic Mode Analysis of Reflectarray Unit Cell

In this work, characteristic mode analysis for unit cells of metal-only periodic structures such as reflectarrays, transmitarrays and frequency selective surfaces (FSS) is presented. Ewald’s representation of three dimensional (3-D) Green’s function for two dimensional (2-D) periodicity is utilized within the Method of Moment (MoM) analysis. Modal characteristics of reflectarray antennas are investigated. Relation between characteristic modes and the reflection coefficients for reflectarray antennas is discussed. It is concluded that the theory of characteristic mode (TCM) can be exploited for the design and analysis of reflectarray antennas.

Characteristic Mode Analysis of Unit Cells of Metal-Only Infinite Arrays
Haykır, Yiğit; Aydın Çivi, Hatice Özlem (2019-09-01)
Characteristic mode analysis of metal only unit cells of periodic structures is performed using Method of Moments based formulation. Ewald's transformation is incorporated for a fast and cost efficient solution and the advantages over spatial Green's function are discussed. The influence of the unit cell size on the characteristic modes is demonstrated. Various metal-only reflectarray elements are compared and their radiation characteristics are interpreted using the theory of characteristic modes. It is sh...
Multiscale Modeling of Thin-Wire Coupling Problems Using Hybridization of Finite Element and Dipole Moment Methods and GPU Acceleration
ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (2020-01-01)
In this article, a hybrid numerical method, called finite element method (FEM) + dipole moment (DM), is presented for efficient solution of multiscale electromagnetic radiation and scattering problems that involve structures with fine features, such as thin-wire antennas or objects. In this method, the FEM is hybridized with the DM approach to help ease certain computational burdens, such as mesh refinement, ill-conditioning, memory overload, and long computation times, when solving multiscale problems with...
Effect of electrolyte/sulfur ratio in the cathode on the electrochemical performance of Li-S batteries
Emerce, Nur Ber; Külah, Görkem; Eroğlu Pala, Damla; Department of Chemical Engineering (2019)
In this study, the effect of electrolyte to sulfur (E/S) ratio in the cathode, which is an important cell design parameter, on the electrochemical and cell- and system-level performance of a Lithium-Sulfur (Li-S) battery is investigated through modeling efforts. First, a 1-D electrochemical model is developed for an isothermal, constant-current discharge of a Li-S cell to predict the voltage at 60% discharge depth. In the model, cathode exchange current density is defined as a linear function of the electro...
Complete and Accurate Discrete Complex Image Approximation of Periodic Green's Function in Layered Media
Adanir, Suleyman; Alatan, Lale (2014-08-01)
The periodic Green's functions (PGF) in layered media can be expressed as an infinite series in terms of the spectral domain Green's functions. The discrete complex image method (DCIM) can be used to approximate these spectral domain Green's functions. In this work, it is demonstrated that the complete and accurate DCIM approximation of the PGF is possible only when the DCIM approximation is obtained through the samples of the spectral domain Green's function along the real k(p) axis. This choice of samplin...
Efficient computation of the Green's function for multilayer structures with periodic dielectric gratings
Adanır, Süleyman; Alatan, Lale; Department of Electrical and Electronics Engineering (2011)
Numerical analysis of periodic structures in layered media is usually accomplished by using Method of Moments which requires the formation of the impedance matrix of the structure. The construction of this impedance matrix requires the evaluation of the periodic Green’s function in layered media which is expressed as an infinite series in terms of the spectral domain Green’s function. The slow converging nature of this series make these kinds of analysis computationally expensive. Although some papers have ...
