| Abstract | The spectral domain technique is used to analyze the coupling characteristics of coplanar waveguide and microstrip lines to highly lossy multilayer dielectric media. The possibility of exciting surface waves and hence generating and coupling nontransverse electric field components is also investigated. It is shown that surface waves will not be excited in the substrate when a high-dielectric lossy media is placed on top of the coplanar structure. In the presence of a superstrate between a high-dielectric lossy medium and the coplanar waveguide, however, the quasi-static TEM and TM/sub 0/ modes may be excited. An axial electric field component can then be coupled to the loss medium. The developed solution was also utilized to optimize the coupling performance of these structures to lossy dielectric media. It is shown that to enhance the EM coupling, higher frequencies should be used, the dielectric constant of the substrate should be small, and the width of the center conductor and the air gaps in a coplanar waveguide should be as large as possible.< |

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.
