Abstract
In this work, we present a unified approach to model the optical response from a classical local and a nonclassical nonlocal hydrodynamic interface. The modeling is based on a boundary integral equation (BIE) representation. This representation is general for both 2D and 3D problems and can be numerically solved by the Method of Moments (MoM) algorithm. An example is then demonstrated for the 2D and 3D case. A very good agreement with the generalized Mie theory has been demonstrated.
