| Abstract | In order to realize the analysis of subsurface constitution by non-destructive detecting methods, one of the best candidates is the GPR (Ground Penetrating Radar). Since some years, it has successfully been used in various applications fields such as in archaeology, geology domains and for civil engineering. More recently, an increasing interest is devoted to the survey of the surface of Mars. We can quote the recent missions Mars Express, Mars Reconnaissance Orbiter and now Aurora. So to discover the history of Mars planet, many missions seek to establish topography of the subsurface. Concerning the ExoMars mission, WISDOM [1] (Water Ice and Subsurface Deposit Information on Mars) consists in a Rover carrying several elements including a GPR. This one contains a radar unit and embedded transmitting and receiving antennas of Vivaldi antennas type [2]and operates in the waveband [0.5 – 3] GHz. In order to prepare the mission and to evaluate the behavior of the antennas, we have to make models of the transmitting antennas mounted on his Rover. The FDTD [3] approach has been chosen for this study. Because it as proven to be one of the most popular techniques reported in the literature to deal with GPR problems. The difference of scale between these two elements arises then. To overcome this problem, it seems unavoidable to establish a representative model of these antennas in their context. To do this, we have developed an electrical dipolar source model coupled to a Huygens surface in the FDTD 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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
