Unexplored Aspect of Velocity of light (2008)
Biswas, Abhijit, Mani, Krishnan RS
In the post-Maxwellian era, sensing that the tide of discoveries in electromagnetim indicated a decline of the mechanical view, Einstein replaced Newton's three absolutes -- space, time and mass,...
Simplified lasercom system architecture using a disturbance-free platform (2008)
Chen, Chien-Chung, Hemmati, Hamid, Biswas, Abhijit, Ortiz, Gerardo, Farr, William, Pedreiro, Nelson
