Simulation of active microdisk antenna using solid state and dispersive models

Metallic nanorods are embedded in semiconductor microdisk in such a way that they direct the field in dipole fashion for near field applications. For the simulation of nanorods Lorentz-Drude (LD) model and for the simulation of semiconductor microdisk solid state model are incorporated into Maxwell equations. The solid state model consists of Pauli Exclusion Principle, state filling and dynamical Fermi-Dirac thermalization. The finite difference time domain (FDTD) method is applied to the approach for analysis of structures.
