Abstract | The harmonic surface acoustic wave (SAW) scattering at 90-degree corners of piezoelectric substrates is studied by FEM. The SAW is incident perpendicular to the vertical border. The dependences of the reflection and transmission coefficients on the radius of the fillet at the corner are found for 128°YX and YZ $LiNbO_{3}$ as well as ST-X quartz substrates. It is demonstrated that if the substrate is anisotropic, then a SAW can be scattered off differently at the right-hand border and the left-hand border. Computations for YZ $LiNbO_{3}$ illustrate possible levels of the anisotropy of the scattering for mutually reverse directions of incidence. However, if the substrate is oriented in a specific manner, then the scattering from the right-hand border is identical to the scattering from the left-hand border. There are four types of such orientations. |

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.
