| Abstract | The authors present a method for the analysis of surface transverse wave (STW) interaction with a finite number of arbitrary rectangular-shaped metallic electrodes (fingers), elastic ridges, and grooves. The metallic fingers having ideal conductivity and isotropic elastic properties are deposited on the surface of an anisotropic piezoelectric substrate supporting a shear horizontal wave. Arbitrary height, width, spacing, and electric polarity of the fingers can be assumed. Based on first principles, a model for the metallic fingers has been developed. In the finger regions the mechanical displacement is decomposed into a finite number of properly chosen eigenmodes, such that on the three free sides of each finger the stress vanishes. The remaining four mechanical and electrical boundary conditions in the substrate interface plane, in conjunction with Sommerfeld's radiation principle in the substrate, complete the set of boundary conditions. A Fourier method combined with the method of weighted residuals has been applied to determine simultaneously the amplitudes of various modes in the fingers and the electrical charge density distribution on the finger surfaces. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
