“…But yet, those methods still lacked full rigor and just gave approximate solutions, as further evidenced by Kriegsmann and McCartin [1996]. In Kim et al [1999], a technique that hybridizes the method of moments with the uniform geometrical theory of diffraction (MOM/UTD) was presented for the analysis of corrugated surface‐wave antennas with an infinite ground plane and fed by a parallel‐plate waveguide. More recent works of Uusitupa [2006], Hanninen and Nikoskinen [2008], and Alfonso et al [2009] described formulations based on the method of moments to analyze the scattering of impingent plane waves from corrugated surfaces.…”

[1] A rigorous but yet highly accurate and efficient numerical treatment of plane wave scattering by T-shaped planar corrugations through full-wave modal analysis is first presented in this paper, which entails the moment method using parallel-plate waveguide cavity Green's functions and a numerical spectral-domain Green's function for planar stratified media. Investigations in terms of both reflection-phase and dispersion diagrams are conducted. After validating with the commercial software package: CST Microwave Studio, this moment-method is in turn used to verify a formula derived by the transverse resonance technique (TRT) for the surface-wave propagation constant of corrugations in terms of the dispersion diagram. Correspondences between the reflection-phase and dispersion diagrams are then established by relating the high and low impedance frequencies in the former with the pass and stop bands of the latter. With the abovementioned formula, the way is paved for a novel derivation of explicit formulas for the reflection-phase of an incident plane wave impingent on the corrugations as closed-form analytic functions of the various parameters, even for oblique azimuth planes of incidence and for both TE and TM polarizations. Doing so, the high or low surface-impedance (AMC or AEC) properties of such corrugations can virtually be acquired instantly, thus providing incomparable speedup of the process of thorough reflection-phase characterization of AMC or high-impedance surfaces and soft surfaces, thus affording rapid designs of antennas and microwave devices that make use of them.Citation: Ng Mou Kehn, M.

“…In 1980, MoM-UTD method was used to analyze the input impedance of wire antennas located near perfectly conducting (PEC) circular cylinders by considering the diffracted rays [6]. From 1980 to 2000, MoM-UTD/GTD method was widely used to solve scattering, radiation, and coupling problems [7][8][9][10][11][12]. In 2001, the hybrid MoM-UTD method was applied to calculate the mutual coupling between apertures on a convex circular cylinder [13].…”

frequencies suggest that these are almost identical in shape, and direction of maximum intensity in each case is normal to the patch geometry. These obtained bandwidth and radiation pattern results suggest that the proposed antenna geometry with further modifications may be a suitable candidate for future wireless communication systems.ABSTRACT: This article presents a new efficient hybrid higher order MoM-UTD method. It overcomes the limitation of traditional MoM-UTD method, which is difficult to be applied to the arbitrary structures because of complex ray tracing. Using the large quadrilateral patches and higher order basis functions, the hybrid method in this article can save much more computer memory than the traditional low-order MoM with RWG basis functions. So, it is feasible for complex and electrically large structures. Good accuracy is achieved as the numerical results illustrated.
