Abstract | Surface plasmon propagation properties for nano-sized metal aperture and nano-wire structures are studied based on the waveguide theory. It is verified that there are only $TM_{0}$ and HE1 mode existing in both structures. For nano-wire structure, however, there is no cut-off radii for both $TM_{0}$ and HE1 mode. On the contrast, there is a cut-off radius for nano-sized silver aperture structure, and even more, there are several characteristic radius coefficients a/lambda, - 0.32, 0.73. For each section, the EM wave may takes on different features, e.g.. totally-bounded features along the aperture interface for a/lambda > 0.73, or oscillation inside core or strong attenuation along z direction for 0.32 < a/lambda <0.73. $HE_{1}$ mode of metal aperture doesn't show cutoff radius as well, but the wave-number along z direction monotonically increase with the radius coefficient a/lambda in contrast with existence of a characteristic radius coefficient a/lambda of 0.41 for nano-wire |

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.
