Abstract

We explore the unusual electromagnetic response of magnetically-biased densely-packed graphene ribbons. Applying an effective medium approach, we show how the presence of a magnetostatic bias induces resonances on all components of the effective conductivity tensor, significantly enriching the features of the supported surface plasmons polaritons (SPPs). Specifically, we demonstrate magnetically-induced non-resonant topoloical transitions at terahertz (THz) frequencies, enabling planar canalization without the influence of large dissipative losses, and we predict the presence of weakly-confined transverse electric SPPs in a narrow band below resonance. Our findings may pave the way towards the development of planar, ultra-sensitive sensors, lenses, non-reciprocal components and imaging systems at THz.
