| Abstract | Fishnet metamaterials consist of two or more conducting fishnet layers separated by homogeneous dielectric layers. Different from other planar multilayer metamaterial structures fishnet metamaterials do not require vias for through-contacting between the layers. This allows low-cost production of three-dimensional metamaterials by spray coating with organic (carbon nanotubes CNTs) or metallic (silver) nano pigment inks. Spray coating has proven to be a low cost fabrication technique for high throughput. Numerical studies are pursued in this contribution to investigate fishnet metamaterial using nano pigment inks. In this work we compare fishnet metamaterial structures fabricated from spray coated layers of variable sheet conductance with fishnet metamaterial structures fabricated from highly conductive material with superimposed homogeneous CNT layers of low sheet conductance. In these cases the spray coated CNT layers allow to adjust the area resistance of the conductive layers for optimum broad-band design. The tunable resistance of sprayed thin films allows for an enhanced tailoring of the effective parameters of the metamaterial structures and, hence, for an enhancement of their bandwidth of negative refractive index. |

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.
