Title: Transverse Terahertz magnetism in 1-dimensional plasmonic system

Speaker: Prof. Dibakar Roy Chowdhury, Mahindra University, Hyderabad

Abstract: In this talk, I will demonstrate transverse magnetism in 1-dimensional (basically, low dimensional system) plasmonic wire. As per general perception, transverse magnetism cannot exist in one dimensional plasmonic systems because of the fundamental limitations imposed by basic electromagnetic theory. Contrary to this general belief, we have recently demonstrated (experimentally and theoretically, both) transverse magnetism in a plasmonic wire constituting a cut-wire pair-based metasurface operating at the terahertz frequencies. Our demonstrated scheme can help in developing compact photonic or electrical integrated circuits besides other futuristic applications, such as, artificial magnetism, cloaking, magnetic storage etc.
