Surface Plasmon Polaritons (SPPs) are electromagnetic waves along the boundary between a metal and a dielectric, typically within the infrared or visible light range. These waves are tightly confined to the interface, with their intensity decaying exponentially perpendicular to the surface. SPPs propagate along the metal-dielectric boundary until they lose energy through absorption in the metal or by scattering caused by surface irregularities, which limits their range and intensity. This confinement allows for applications that require high spatial resolution, such as imaging and nanophotonics. Metamaterials, when paired with SPPs, provide advanced control over light-matter interactions, enabling the efficient guidance of plasmonic waves along complex structures. Hyperbolic metamaterials exhibit high anisotropy and can support SPP propagation over longer distances with reduced losses, making them valuable in sensing and imaging technologies. This paper explores active metamaterials to control SPPs dynamically, adjusting plasmonic properties in response to external signals. This study is to pave the way for reconfigurable plasmonic devices and tunable nanophotonic systems, as the combination of SPPs and metamaterials is opening new horizons in nanotechnology. It allows for ultra-compact, efficient, and highly sensitive devices that operate at the edge of conventional light manipulation capabilities.
