| Abstract | This paper presents a generalization of the Oliner's method used to investigate the guided modes supported by a Sinusoidally-Modulated Surface Reactance (SM-SR). In its original paper, Oliner applied the procedure to the case of a scalar and impenetrable impedance sheet in free space; in this work, this approach has been extended to find the guided mode configurations (both leaky and surface waves) for the more general case of Sinusoidally-Modulated Tensor Surface Reactance (SM-TSR), placed inside a generic dielectric stratification. SM-TSR can be seen as the simplest version of metasurface able to realize leaky-wave antenna with circular polarization. The results obtained have been successfully compared, in terms of complex propagation constant and polarization, with those of actual sinusoidally modulated metasurfaces constituted by small printed element over a ground dielectric substrate. These first results confirmed the possibility to use the SM-TSR as local canonical problem for the analysis of more complex metasurfaces. |

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.
