| Abstract | Previous investigations on $KTa_{1-x}Nb_{2}O_{3$ (KTN) materials evidenced the need to gain insight into the dielectric properties of these films to realize tunable functions with high electrical performances. We, thus, developed a simple and efficient method to determine their dielectric properties at microwave frequencies. It is based on the measurement and analysis of coplanar waveguides (CPWs). The complex permittivity of the film was determined from a modified spectral domain approach. This method was applied, here, to evaluate the permittivity and losses of $KTa_{0.6}Nb_{0.4$ $}O_{3}$ thin-films deposited on different substrates. The comparison of these results with structural analyses enabled us to observe the influence of the microstructure on the microwave dielectric properties |

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.
