| Abstract | It is current practice to match a given discontinuity in waveguide by means of an identical one (matching element) placed a quarter-wavelength away from the first. For accessible discontinuities, a superior technique consists in placing two matching elements symmetrically with respect to the (symmetric) discontinuity, so that they are seen as its dual. Usually a discontinuity behaves as a nonresonant element, for instance a lumped capacitance. Then its dual is also "lumped" and must be placed at the location of the discontinuity, with hardly ary length of waveguide interposed. Due to interaction via higher-order modes, a two-port representation of the individual discontinuities no longer holds. Therefore application of the new matching technique requires accurate, wideband, finite multiport equivalent circuits of the discontinuities. As an example, it is shown numerically and experimentally how an iris with original reflection coefficient of 40% can be matched over the whole waveguide band with a residual reflection ¿2%. |

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.
