Abstract | A planar resonant slot antenna with a ground plane aperture was developed for nondestructive testing of planar dielectric materials. Using an existing design methodology, a circuit was developed where the complex permittivity could be determined from the shift of the resonant frequency and knowledge of the thickness of the test substrate. The device was simulated using the method of moments and these simulations validated experimentally. The electric field around the aperture has also been investigated by simulation and measurement. It was found that the substrate manufacturers' values for the permittivity and tan /spl delta/ and the values as determined using this work are in agreement. In addition, the permittivity of carbon fibre composite (CFC) and nanoclay polymer substrates has also been investigated using this method. |

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.
