| Abstract | The current design trend away from aluminum skinned aircraft and toward composite materials has the potential to leave new aircraft vulnerable to electromagnetic interference. While traditional aluminum skin provides significant shielding to the electronics inside the aircraft, however, carbon-fiber composite aircraft provide substantially less shielding. This suggests the growing importance of characterizing, measuring and predicting the shielding effectiveness provided by the composite skin of an aircraft. The current practice of characterizing the shielding effectiveness of a fuselage in the prototyping phase leaves manufactures vulnerable to costly shielding mitigation and redesign work. This paper proposes a virtual measurement to help predict the shielding effectiveness during the design phase when changes are simpler and more cost effective. To demonstrate the rigor of the proposed virtual measurement method, the shielding effectiveness of a carbon-fiber composite uncrewed aircraft was measured in an industrial reverberation chamber. These qualified shielding effectiveness measurements then serve as a benchmark with which to compare the virtual measurement results. In making this comparison some interesting results between reverberation chamber and direct illumination shielding effectiveness came to light. This paper presents the virtual measurement method, the model validation work and early shielding effectiveness measurement comparisons. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
