Abstract Scope I will present theoretical investigations on mono-layer borophene plasmons at optical frequencies. Borophene has recently expanded the 2D materials family after its successful deposition on silver substrates. We theoretically investigate the plasmonic properties of nanostructured monolayer borophene using full-field electromagnetic simulations and demonstrate that borophene nanoribbon and nanopatch arrays can support localized plasmon resonances at visible and near-infrared wavelengths. Due to its puckered crystal structure and vacancy distribution in hexagonal lattice, borophene exhibits strong anisotropic in-plane properties which makes it an unconventional plasmonic material. I will also introduce MoO3 as an anisotropic photonic and polaritonic material. MoO3 is a layered material that exhibits both in and out-of-the-plane anisotropic polaritonic response at mid-IR wavelengths. We designed and experimentally demonstrated an anisotropic polaritonic absorber and showed that one can couple to all phonon modes and address them individually either using structural tunability or polarization control of incident infrared radiation.
