This paper compares between different efficient and accurate techniques for the numerical analysis of a 1D periodic printed structure with the method of moments (MoM). Both a hybrid spatial/spectral and a purely spectral approach are examined, the former via the discrete complex image technique (DCIT) and the latter through suitable asymptotic extractions and numerical acceleration schemes. These fast formulations are particularly suitable for studying the excitation of the considered structure by a-periodic sources via the array-scanning method (ASM) in the work of Munk and Burrell (1979). As is known, the ASM requires as intermediate steps the solution of many Floquet-periodic problems, which can be efficiently treated with the proposed MoM approaches.

Abstract
This paper compares between different efficient and accurate techniques for the numerical analysis of a 1D periodic printed structure with the method of moments (MoM). Both a hybrid spatial/spectral and a purely spectral approach are examined, the former via the discrete complex image technique (DCIT) and the latter through suitable asymptotic extractions and numerical acceleration schemes. These fast formulations are particularly suitable for studying the excitation of the considered structure by a-periodic sources via the array-scanning method (ASM) in the work of Munk and Burrell (1979). As is known, the ASM requires as intermediate steps the solution of many Floquet-periodic problems, which can be efficiently treated with the proposed MoM approaches.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
