This work presents a novel technique for efficient numerical modeling of electromagnetic scattering from metasurfaces comprising of truncated periodic or locally-varying quasi-periodic surfaces. The proposed technique hybridizes the periodic Finite Element Method (FEM) with the Method of Moments (MoM) to develop an algorithm far more efficient than conventional numerical methods for electromagnetic scattering from arbitrary objects. The key feature of the proposed algorithm is that it takes advantage of the quasi-periodic nature of metasurfaces to derive high-level Macro Basis Functions (MBFs) derived by using the FEM, and subsequently used to derive a reduced MoM matrix for the unknown coefficients of the MBFs. Numerical results are derived and validated by comparing them with those obtained from commercial softwares.

A Numerical Model for Investigating the Effect of Rough Surface Parameters on Radar Cross Section Statistics
Kuzuoğlu, Mustafa (2017-07-14)
Electromagnetic scattering from rough surfaces is modeled by combining the periodic finite element method and the transformation electromagnetics approach. The behavior of the radar cross section (RCS) at both specular and backscattering directions is analyzed as a function of rms height and correlation length with the help of Monte Carlo simulations. The concept of backscattering enhancement is illustrated, and some conclusions are drawn about the RCS statistics.
A Transformation Media Based Approach for Efficient Monte Carlo Analysis of Scattering From Rough Surfaces With Objects
Ozgun, Ozlem; Kuzuoğlu, Mustafa (2013-03-01)
This paper presents a computational model that utilizes transformation-based metamaterials to enhance the performance of numerical modeling methods for achieving the statistical characterization of two-dimensional electromagnetic scattering from objects on or above one-dimensional rough sea surfaces. Monte Carlo simulation of the rough surface scattering problem by means of differential equation-based finite methods (such as finite element or finite difference methods) usually places a heavy burden on compu...
A novel CEM technique for modeling electromagnetic scattering from metasurfaces
ÖZGÜN, ÖZLEM; Mittra, Raj; Kuzuoğlu, Mustafa (Wiley, 2020-03-01)
This paper presents a novel computational electromagnetics (CEM) technique, which hybridizes the periodic finite element method (FEM) with the method of moments (MoM), for efficient numerical modeling of electromagnetic scattering from metasurfaces consisting of truncated periodic or locally varying quasi-periodic array of structures. Based on the quasi-periodic nature of metasurfaces, the periodic FEM is employed to generate high-level macro basis functions (MBFs). Following that, a reduced MoM matrix is f...
An efficient hybrid UTD-MoM analysis of radiation/scattering from large truncated periodic arrays
Aydın Çivi, Hatice Özlem; Chou, HT (1998-01-01)
A hybrid method is described which combines a previously developed UTD ray analysis for periodic structures with the conventional numerical MoM approach to efficiently analyze the radiation and scattering from electrically large finite arrays. The UTD, which constitutes an asymptotic high frequency ray solution, is extended to describe the fields of an entire large planar array (consisting of a very large number of elements) in terms of just a few rays which an relatively independent of the physical size of...
A coordinate transformation approach for efficient repeated solution of Helmholtz equation pertaining to obstacle scattering by shape deformations
Ozgun, Ozlem; Kuzuoğlu, Mustafa (2014-06-01)
A computational model is developed for efficient solutions of electromagnetic scattering from obstacles having random surface deformations or irregularities (such as roughness or randomly-positioned bump on the surface), by combining the Monte Carlo method with the principles of transformation electromagnetics in the context of finite element method. In conventional implementation of the Monte Carlo technique in such problems, a set of random rough surfaces is defined from a given probability distribution; ...
