| Abstract | A filter optimization strategy based on full wave EM simulations is proposed. With the introduction of additional internal ports in the filter model, the multi-port admittance-matrix (Y-matrix) is obtained. The main advantage lies in the fact that the filter's basic parameters, as there are the resonant frequency of each resonator, the coupling coefficients and the external Qs are directly accessible through the multi-port Y-matrix. These values are known to give a broad insight into the filter and allow a straightforward optimization procedure to meet the specified data of the synthesis. Furthermore, parasitic effects and design restrictions can be identified and even quantified. Here, an example of a combline filter with a six pole Chebyshev characteristic has been chosen to demonstrate the technique and to verify the method, which can be adapted to other types of filters as well as to other characteristics. Based on this example, a parasitic external coupling was identified and compensated illustrating the advantages of this method. |

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.
