Scattering of inhomogeneous cylinders by circuital analysis

Abstract

Circuital analysis theory is applied to solve problems of electromagnetic diffraction in nonhomogeneous cylinders. The MAG of a simple element, the circular sector, is calculated as the primary element in the segmentation of greater problems. Circuital theory applied to these problems allows us to resolve problems of greater size and difficulty. © 2003 Wiley Periodicals, Inc.

Full-Wave Analysis of Dielectric-Loaded Cylindrical Waveguides and Cavities Using a New Four-Port Ring Network

“…For complex or large size waveguides or cavities, however, the MM method may suffer from convergence problems, and it has been combined with other analytical techniques [29][30][31][32]. Circuit analysis and segmentation have also proved to be powerful tools for analyzing complex dielectric-filled structures [33][34][35]. The generalized circuital analysis is a method for solving electromagnetic problems that consists of the segmentation of the whole geometry of the microwave structure into simpler elements, which then can be solved in an easier way [25,[36][37][38][39][40][41].…”

Circuital Analysis of Cylindrical Structures Applied to the Electromagnetic Resolution of Resonant Cavities

“…Another interesting example is the work of (Gentili & Melloni, 1996). Some other examples can be found in (Alessandri et al, 1994), (Gimeno & Guglielmi, 1997) y (Rebollar et al, 1994) for closed structures and in (Valero-Nogueira 1997), (Penaranda-Foix, 2001), (Penaranda-Foix & Ferrando-Bataller, 2003), (Penaranda-Foix et al, 2007a) y (Penaranda-Foix et al, 2009) for open problems. Figure 2a shows a generic example for illustrating how the circuital theory can be applied to solve complex structures.…”
