Abstract | The microwave invasion into living bodies at a millimeter wave irradiation using gyrotron as the radiation power source is described. The irradiation antennas of the system consist of a Teflon rod dielectric antenna, and a Teflon sheet dielectric antenna set at 2.4 - 5.0 mm diameter catheter waveguide vent. Preliminary measurements on the denaturation distribution of irradiated caw livers suggest that they are suitable for common irradiation apparatus for living bodies in similar case as previous report. [1,2] The power absorption of a living body surface is large in these wavelength regions, because the reflections of the wave are well hold down (impedance-matching) by the anti-reflecting layers (ARL) of dielectrics. [3] We measured the power changing of millimeter wave with ARL antennas thickness by some TE modes using gyrotrons. Transmission tests through catheter waveguides confirm the normal operation of the irradiation apparatus for living bodies. |

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.
