| Abstract | A numerically efficient finite-element procedure is developed for solving general waveguide structures loaded with isotropic materials. The procedure is straightforwardly derived from the vectorial Helmholtz wave equation. In this procedure, a formulation derived in terms of the transverse magnetic field components, satisfying Maxwell's divergence equation and satisfying the boundary condition, is adopted. The eigenvalue of the final matrix equation corresponds to the propagation constant, while the eigenvector represents the corresponding propagation field mode. A dielectric-filled rectangular waveguide with highly conductive walls is studied, and the error induced by using the finite-element method is analyzed and studied in detail. This error is compared with that obtained in previous work by others. It is concluded that this efficient computer-aided solution procedure can be used in the analysis of electromagnetic wave propagation in an anechoic chamber. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
