| Abstract | The growing bandwidth of optical communication systems has made great improvements to information technology infrastructures. However, electro-magnetic compatibility becomes an issue due to the high frequency of the components. EMI problems occur due to the miniaturization and high density of the Printed Circuit Board (PCB) mounted on the system. Generally, electro-magnetic radiation is generated by the circuit elements. For example, switching in the LSI raises the voltage swing between the power source and ground which is known as “ground bounce”. EMI problems related to the ground and power source are linked to the power integrity, and is influenced by the structure of the patch antenna parasitically existing between the power source and ground. That is to say, most of the time this problem can be solved by utilizing the appropriate power source and ground pattern layout at the PCB design stage. However, high speed digital signals measuring at more than 10 Gigabit per second (Gbit/s) typically have high frequency components in excess of 40GHz. There is little feasible knowledge available that illustrates guidelines for the perfect layout method to prevent the emission on the PCB for such a high frequency application. Therefore, we focused on the Finite Element Method used in the 3D electromagnetic field analysis simulator so that we could solve the emission within the frequency domain. We first correlated both qualitatively and quantitatively the actual measurements and the simulation results. Then we investigated the countermeasure for the emission intensity (EMI level) from the 10 Gbit/s optical transceiver by simulation and then verified it. |

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.
