Original abstract

Unusual properties of novel two-dimensional materials like graphene have revolutionized many branches of science and technology. Adequate numerical simulations of photonic devices comprising graphene layers require new approaches or modified methods. We present detailed comparison of results obtained with three representations of a graphene monolayer: (i) an infinitely thin sheet with a finite surface complex conductivity, (ii) a thin layer of a finite thickness exhibiting uniaxially anisotropic complex permittivity, and (iii) permittivity perturbation in an infinitely small volume.

Neobvyklé vlastnosti nových dvourozměrných materiálů, jako je grafen, způsobily revoluci v mnoha oborech vědy a techniky. Adekvátní numerické simulace fotonických zařízení obsahujících grafenové vrstvy vyžadují nové přístupy nebo modifikované metody. Předkládáme podrobné srovnání výsledků získaných pomocí tří reprezentací monovrstvy grafenu: (i) nekonečně tenká vrstva s vodivostí konečnou vodivostí, (ii) tenká vrstva konečné tloušťky vykazující jednoosou anizotropní komplexní permitivitu a (iii) porucha permitivity v nekonečně malém objemu.
