..., scientific and medical applications (Thuery, 1992), which usually require the participation of human beings in direct contact with microwave equipment. In particular, industrial microwave ovens often employ open‐ended waveguide systems in order to allow a continuous flow of the material to be processed. Thus...

..., provide the same kind of reliable approximation. © MCB UP Limited 2002 Waveguide Eigenvalues Finite elements Electromagnetics In this paper we address the issue of spurious modes which may appear in finite element approximations of electromagnetic eigenproblems (Pinchuk et al...

... to several practical problems including scattering at the edge of a wall and over periodic grids or grooves, wave propagation along a dielectric structure, and a mode coupling between two parallel optical waveguides. The TLM solutions are compared with the theoretical ones or the results of other numerical...

...N.V. Kantartzis; T.V. Yioultsis; T.D. Tsiboukis The narrow‐wall inclined‐slot coupling between rectangular waveguides from an H‐plane T‐junction, is numerically analysed, for the first time, via a 3D generalised locally conformed FDTD technique. The structure is excited by a combined pulsed...
