| Abstract | Effective complex permittivity measurements of liquids are important in microwave engineering, microwave material processing, microwave chemistry, and electrobiology. Artificial neural network computational modules have recently gained recognition as an unconventional and useful tool for microwave technology. Neural networks can be trained to learn the behavior of the effective complex permittivity of the liquids under irradiation of microwave. It can provide a fast and accurate answer to the task when it has learned. In this paper, we present a simple and convenient method for determining the effective complex permittivity. First, we use a resonant coaxial sensor to measure the reflection coefficients, to check its performance, the electromagnetic field distribution near the sensor and the reflection coefficient is calculated employing the frequency dependent finite difference time domain method. Second, we develop an artificial nerve network and enough simulated materials are utilized to train the networks. Finally, the trained network is employed to predict the effective complex permittivity of liquids, and compare the parameter with pure water obtained from Debye's equation. Results are presented and discussed. |

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.
