| Abstract | In this paper, two transitions between a coaxial line and a thin water layer are presented: one with symmetric structure and the other for a unidirectional wave propagation. In order to have a smooth transition and to achieve a wide bandwidth, an inverted glass cone is employed in the axially symmetric transition between a coaxial probe and a thin water layer. For the unidirectional design, a parabolic cavity made of a thin glass layer is added at one side of the water layer to reflect the electromagnetic waves to the desired direction. Simulation results show that omnidirectional and unidirectional propagation of electromagnetic waves can be successfully excited in the thin water layer through these two transitions respectively. The 10 dB bandwidths from 454 MHz to 914 MHz (67.3%) for the symmetric transition and from 463 MHz to 915 MHz (65.6%) for the unidirectional transition are obtained. |

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.
