| Abstract | The author presents an overview of the physical properties of thin film resonators, composite resonators using piezoelectric thin films, and filters employing coupled resonators. There are both similarities and substantial differences between thin-film resonators and conventional single-crystal resonators used at low frequencies. For most applications the thin-film resonator is fabricated with lateral dimensions in excess of 50 to 100 times the thickness and as such can be considered a one-dimensional device for the purposes of wave propagation and circuit modeling. Composite resonators consisting of piezoelectric films supported by membranes or bulk substrates form an important part of the thin-film resonator technology. An analysis of the general quasi-mode composite resonator is presented, and the results are summarized in electrical impedance equations cast in a matrix algebra format.< |

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.
