Strong transient magnetic fields induced by THz-driven plasmons in graphene disks
Jeong Woo Han, Pavlo Sai, Dmytro But +10
Strong circularly polarized excitation opens up the possibility to generate and control effective magnetic fields in solid state systems, e.g., via the optical inverse Faraday effe…
Polarization independent lattice-coupled terahertz toroidal excitations
Angana Bhattacharya, Bhagwat S. Chouhan, Bhairov K. Bhowmik +2
The toroidal dipole excitation is an important field for metamaterial research because of their low-loss attribute. In this study, we demonstrate numerically and experimentally, a…
Plasmon induced transparency in an air-dielectric grooved parallel plate terahertz waveguide
KM Dhriti, Maidul Islam, Angana Bhattacharya +2
In this article, we examine plasmon induced transparency (PIT) effect in a parallel plate waveguide (PPWG) comprising of two similar pyramidal shaped grooves. One of the grooves is…
Surface polaritonic solitons and breathers in a planar plasmonic waveguide structure via electromagnetically induced transparency
Koijam Monika Devi, Gagan Kumar, Amarendra K. Sarma
We propose a scheme for the coupler-free excitation of surface polaritonic solitons and breathers in a planar plasmonic waveguide structure comprising of a transparent layer, a met…
Plasmon induced transparency in graphene based terahertz metamaterials
Koijam Monika Devi, M. Islam, Dibakar R. Chowdhury +2
Plasmon induced transparency (PIT) effect in a terahertz graphene metamaterial is numerically and theoretically analyzed. The proposed metamaterial comprises of a pair of graphene…
Enhanced terahertz transmission through a periodic array of tapered rectangular apertures
Koijam Monika Devi, Amarendra K. Sarma, Gagan Kumar
We numerically analyse extraordinary terahertz transmission properties of an array of rectangular shaped apertures perforated periodically on a thin metal film. The apertures are t…
