| Abstract | Practical aspects of effective generation of short electromagnetic pulses (EMP) and improvement of radiation efficiency are discussed in this paper. Descriptions of the EMP radiation based on the Poynting vector definition and energy transformation are presented below. Antennas classification based on energy behavior in the radiating system is proposed and discussed. Properties of kinetic energy accumulated antennas are analyzed. To generate electromagnetic pulse the kinetic energy accumulated antenna is combined with such opening switch as drift step-recovery diode (DSRD). Operation principles of the DSRD are discussed. Criteria of diodes selection for its application in drift step-recovery (DSR) mode are proposed and described. Methods of provision the DSRD operation condition with a balanced current driver are developed and analyzed. A prototype of antenna–generator that utilizes proposed operation principles was designed, developed and examined. Waveform and power spectrum are presented. Peak power more than 1 kW was achieved on the antenna terminal with 3 ns pulse duration and up to 200 kHz pulse repetition frequency (PRF). The prototype's power consumption didn't exceed 4 W under 100 kHz PRF condition. The proposed approach allows producing of stable nanosecond electromagnetic impulses with hundreds kilowatts peak power and PRF up to hundreds kHz. |

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.
