| Abstract | In this paper, we study the electromagnetic wave propagation in a parallel plate waveguide with rough surface walls, using a mode matching technique in combination with the method of moments (MoM). In the formulation, a line source in the smooth section of the waveguide excites a summation of modal fields. For each waveguide modal excitation, the modal response fields in the rough surface section of the waveguide are obtained by the solution of the governing surface integral equations through MoM. The total field distribution in the rough surface waveguide is a linear combination of the modal response fields. The coefficients are obtained by enforcing the continuity of tangential electric and magnetic fields at the junctions between smooth and rough surface waveguide sections. Results are illustrated for a variety of roughness spectra based on the parametric generalized power spectral density. The results are compared with the previously developed small perturbation method of second order (SPM2) results for the plane wave and waveguide models. With the numerical validation, the SPM2 waveguide model is proved to be able to capture the waveguide thickness effect especially for very rough surface profiles. |

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.
