“…Among those techniques are the integral equation formulation, partial differential equation formulation, and hybrid techniques [3][4][5][6][7]. Furthermore, a rigorous solution had been introduced to solve the scattering problem from an array of dielectric or conductor cylinders for a plane wave excitation of normal incidence [8][9][10][11]. In a previous work [12], the principle of equal volume model was used to model any two-dimensional cylindrical object of arbitrary cross section by an array of circular cylinders.…”

Abstract-A rigorous semi-analytical solution is presented for electromagnetic scattering from an array of circular cylinders due to an obliquely incident plane wave. The cylinders are illuminated by either TM z or TE z incident plane wave. The solution is based on the application of the boundary conditions on the surface of each cylinder in terms of the local coordinate system of each individual cylinder. The principle of equal volume model is used to represent cylindrical cross-sections by an array of circular cylinders for both dielectric and conductor cases in order to proof the validity of the presented technique.

“…The scattering of electromagnetic plane wave from single and array of cylinders for both normal [1][2][3][4][5][6][7][8][9] and oblique [10,11] incidence had been studied for many years. In a previous work [12], the principle of equal volume model was used to model any two-dimensional dielectric object of arbitrary cross section by an array of dielectric circular cylinders.…”

Abstract-A rigorous semi-analytical solution is presented for electromagnetic scattering from an array of parallel-coated circular cylinders of arbitrary radii and positions due to an obliquely incident TM z plane wave excitation. In order to check the validity of this technique, the radar cross-section of a single coated cylinder, a linear array of cylinders, and an arbitrary position array of cylinders are calculated and compared with available data in the literature. Furthermore, the near field is calculated to prove the validity of the boundary conditions on the surface of any cylinder with obliquely incidence wave. As an application, circular metamaterial cylinders are used to show the effect of metamaterial characteristics in altering the forward and backward scattering and in focusing the near field around the objects. 286Henin, Al Sharkawy, and Elsherbeni

“…The GTD diffraction coefficients were used to calculate the fields scattered from the edge so its effect could be included in an lE model for which the unknown current remained only that on the antenna. Other hybrid models have combined DEs and IEs [36], modal expansions and lEs [37], and low-frequency results with IEs [38], as well as extended the GTD-IE models [39], [40], [41], [42]. The basic motivation for development of such hybrid approaches is the goal of modeling each of the separate parts of a complex problem with a technique that is best suited to its particular characteristics.…”

The article presents a brief analytical background, and summarizes the essential ingredients of the method of moments, for numerically solving low.frequency antenna problems. Some extensions to the basic models of perfectly conducting objects in free space are also summarized, followed by a consideration of some of the some computational issues that affect model accuracy, efficiency and utility. A variety of representative computations are then presented to illustrate various modeling aspects and capabilities that are currently available. A fairly extensive bibliography is included to suggest further reference material to the reader.Low-Frequency Antenna Models, Proc. IEEE '91,
