plasmanolike
Plasmanolike is a term used in nanophotonics and materials science to describe optical excitations that resemble plasmons but are not universally classified as true plasmons. In practice, plasmanolike modes refer to collective oscillations of charge that produce a strong resonance in the optical spectrum and exhibit field confinement similar to plasmonic phenomena, yet arise from systems where the classical definition of a plasmon is modified by geometry, material structure, or interaction effects.
These modes can occur in a range of materials and structures, including metal nanoparticles, doped semiconductors,
Key characteristics of plasmanolike excitations include strong optical field enhancement, tunable resonance frequencies, and sensitivity to
The term plasmanolike is not universally standardized and is used variably in the literature. Some researchers
