Recent advancements in nanophotonics are moving beyond isotropic noble metals to achieve dynamic and directional control over plasmons. Conventional localized surface plasmon resonances (LSPR) are limited by their isotropic permittivity and geometry-dependent resonance tuning. Introducing strong material anisotropy offers an effective alternative strategy, providing an additional degree of freedom for controlling plasmon propagation and confinement.
