| Abstract | In this paper, we report the intrinsic characteristics of conducting polymer for gas-sensor at high frequency region, i.e., 500 MHz to 10 GHz. To investigate the high-frequency characteristics of conducting polymer (CP), a coplanar waveguide electrode (CPW) is utilized. First, a CPW without CP, i.e., an open CPW, is simulated by a full-wave electromagnetic solver. From the simulated and measured result, we find that the open CPW shows clearly capacitive component. For a CPW with CP, it shows constant transmission characteristic of approximately 3-4 dB level at overall frequency region. This indicates that CP may be a good sensing material for detection of various gases or vapors in the high frequency region because its electrical properties can be sensitively varied with surface modification of gas absorption and desorption. As a result, if CP is possible to realize the various radio-frequency (RF) circuits and devices, we suggest that it can be used for diverse RF gas- as well as bio-sensing applications. |

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.
