However, it is possible to beat this 'diffraction limit' by guiding light in the form of surface plasmon polaritons ... An SPP is a light wave trapped at the metal/dielectric interface owing ...

compared to Surface plasmon resonance (SPR). In SPR signals are rapidly attenuated and reduced to a limited number of interactions. In GCI the evanescent field travels along the entire waveguide ...

This study introduces a highly sensitive and reconfigurable sensor based on a single spoof localized surface plasmon (LSP) resonator. Exceptional points are unique spectral singularities where ...
