Resonant Electric-Magnetic Toroidal Duality in Height-Modulated Hexagonal Metasurfaces
Oleksiy Breslavets, Yuri Savin, Zoya Eremenko
Toroidal modes enable high-Q resonances, but electric toroidal excitations remain unexplored compared to magnetic ones. This work establishes electric-magnetic toroidal duality in…

Increasing The Sensitivity of a Surface Plasmon Resonance Sensor using Ti3C2 Mxene
Rostyslav Terekhov, Zoya Eremenko, Sergii Kulish
Sensors based on the phenomenon of surface plasmon resonance have limited sensitivity, up to 123 degree/Refractive Index Unit, which restricts their applicability in detecting subt…

Enhancing the Propagation Length of Graphene Surface Plasmon Polaritons using a Metamaterial Substrate with a Near-Zero Refractive Index
Zoya Eremenko, Igor Volovichev
This paper aims to investigate the conditions necessary to control, enhance, and modify the propagation length of graphene surface plasmon polaritons (SPPs) at room temperature, us…
