Coupled resonance via localized surface plasmon polaritons in Iridium-based refractory metamaterials

Plasmonic metamaterials (MMs) have enabled their novel applications across numerous engineering fields ranging from photodetecting to bio-imaging, cancer diagnosis, and photovoltaics. However, as a vast majority of reported plasmonic MMs are based on materials with relatively low melting point such Au or Ag, utilities limited for lower-temperature applications. Thus, realizing resonance refractory will further extend higher-temperature environments. In this work, we numerically report built Ir HfO2, which well-known highly materials. These resonate selectively the excitation localized surface plasmon polaritons magnetic resonances. The wavelength where occurs can be modulated by changing width top metal structure. Moreover, find that metal’s in polynomial relationship over range studied. Therefore, tunable properties, work present potential devices
