Abstract
The transmission properties of electromagnetic wave through left-handed material (LHM) have been thoroughly investigated. The characterization of signal propagation and evanescent wave amplification through LHM slab has been done on the basis of analytical model equations. The transmission properties have also been addressed from the study of group and phase indices, and anomalous dispersions regions in LHM and right-handed material. Furthermore, the orthogonality of electric and magnetic fields of classical electromagnetism has been seen to be applicable for electric and magnetic plasma buffered by a left-handed (LH) medium.

Subal Kar
Subal Kar obtained B.Sc.(Hons.) in Physics from St. Edmunds’ College, Shillong, Gauhati University, and B.Tech., M.Tech., Ph.D(Tech.) from the Institute of Radio Physics and Electronics (IRPE), Calcutta University (C.U). Presently he is Professor of the Institute of Radio Physics and Electronics, C.U.
His field of specialization covers electromagnetism including metamaterials (i.e left handed material, LHM), microwave and millimetre-wave devices and circuits, THz imaging, optical communication, and high energy physics. He has published a large number of research papers in peer reviewed international journals and presented invited papers in France, Poland, Japan, China, and U.S.A. He has three patents to his credit for innovative developments of IMPATT oscillators, amplifiers and power combiners.
He received the Young Scientist Award of URSI and IEEE MTT and he is also the recipient of Fulbright Award of U.S Government. He worked as a Visiting Scientist at Kyoto University, Japan in 1997 and as a Visiting Fulbright Scientist at Lawrence Berkeley National Laboratory, University of California at Berkeley, U.S.A during 1999-2000. He has been listed in Who’s Who in Science and Engineering, published by Marquis’s publication, U.S.A., and in 2000 Outstanding Scientists of the 20th Century, published by International Biographical Centre, Cambridge, U.K.
He has actively participated during his Fulbright tenure at Berkeley lab, in the design of the R.F. cavities for Muon Collider to be operative at Berkeley lab, U.S.A, tentatively by 2012. Since 2004 he is collaborating with the Accelerator and Fusion Research Division of Berkeley lab for the design and development of Laser-based Ultra-fast X-ray source ( LUX ) which will be a sub-nanometre diagnostic facility with possible applications in all branches of science.
He is a Fulbright Fellow, Senior Member of IEEE, Fellow of IETE, Fellow VEDA Society. E-mail: [email protected]
