| Abstract | Both the reflection and the refraction of harmonic inhomogeneous plane waves on a fluid/anisotropic solid interface are described in the framework of linear acoustics. The reflection coefficient is obtained and discussed for different heterogeneity of the incident wave. As for the isotropic case, recently treated, the most significant differences between homogeneous and inhomogeneous incident waves occur at both positive and negative Rayleigh angles. The Rayleigh angle dip phenomenon is visible at the positive Rayleigh angle. At the negative Rayleigh angle this dip is converted into peak, i.e., the reflection coefficient is greater than unity. However, the experimental investigation on a carbon-epoxy sample, does not reveal this peculiar behavior. Damping and high anisotropy of the material explain the phenomenon observed near the Rayleigh angle |

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.
