Abstract | This study presents a three-dimensional near-field measurement system to measure surface waves using LabVIEW. The system is based on the capacitive coupling between metasurface and the electric probe, which is optimised to increase signal-matching efficiency. In order to realise three-dimensional near-field measurements, the scanner is composed of three-axis sliding rods and three stepping motors to drive the near-field probe. Especially, the double position/signal difference method is used to obtain a high spatial resolution. The system is controlled by LabVIEW to realise automatic measurement so that the electric magnitude and phase distribution can be displayed in real time. Finally, a spoof surface plasmon polariton coupling metasurface sample is measured by the system. The measurement results of surface waves are in good agreement with the simulation. |

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.
