“…First, we have computed and compared the dispersion diagram and the interaction impedance of elliptical corrugated waveguides presented in [16] and [18]. Second, with our novel characterization method, we have studied the effects, in the k 0 −β diagram, of two nonconfocal periodic elliptical waveguides by shifting the elliptical iris in the x-and y-axes, respectively.…”

“…In this paper, the authors use space harmonic effects and the field matching method to compute the field components, ignoring higher-order modes in the slot region. Therefore, all the results presented in [16] are refereed to the fundamental lowest symmetric ( e T M 01 for the elliptical case or T M 01 for the circular one) mode. Fig.…”

“…Raevskii and Smorgonskii and Belov et al studied the structure characteristics as a microwave transmission line [14], [15]. Xu et al studied, using a field-matching method, the fundamental mode of the corrugated elliptical waveguide by taking no account of space harmonics, as well as neglecting higher-order modes in the slot region [16], [17]. Recently, Han et al have studied [18], by following a modematching approach, the dispersion characteristics of three even TM modes, considering space harmonics in the inner region and higher-order modes in the slot region.…”

Abstract-In this paper, a novel full-wave method for the modal characterization of periodic structures loaded with elliptical waveguides is presented. This method relies on an integral equation formulation solved via the method of moments, which finally leads to the solution of a standard eigenvalue problem. The required modal spectrum of elliptical waveguides is determined through the boundary integral-resonant mode expansion technique. For validation purposes, the proposed analysis method is first successfully applied to periodic waveguide structures already considered in the technical literature. Then, our new algorithm is used to compute the related Brillouin diagrams and the interaction impedance of new periodic structures loaded with elliptical waveguides. Not only the main interacting mode (such as the T M 01 mode) is studied, but higher-order Floquet modes are also considered. These results have potential applications as slow-wave structures for high-power microwave devices and possibly filtering structures at millimeter-wave frequencies.

Abstract-Corrugated elliptic waveguide in actually extensive application is analyzed by using the mode matching method and Mathieu function. Considering space harmonics in the interior and higher order modes in the slot region of the corrugated elliptic waveguide, the dispersion equation of even TM modes is derived. The dispersion and attenuation characteristics as well as the influence of passband and stopband properties with the changes of structural parameter are investigated in detail. The calculated results in good agreement with ones in the relevant references are of very important values in theoretical studies and actual applications of corrugated elliptic waveguide for microwave engineering.
