Abstract: When two structures are within sub-nanometer distance of each other, quantum tunneling effect becomes relevant. These effects cannot be accurately modeled by classical electromagnetic solvers. In this study, an auxiliary tunnel that connects the structures is introduced to model the quantum tunneling effect. The quantum model of the tunnel is obtained using density functional theory (DFT) computations, which account for the atomic structure of materials. The plasmonic fields on the resulting connected structure are analyzed using a time domain surface integral equation solver. Time domain samples of the dispersive medium Green function and the dielectric permittivities are computed from the analytical inverse Fourier transform applied to the rational function representation of their frequency domain samples. Numerical results, which demonstrate the effect of the quantum correction on the transient electromagnetic interactions, will be presented.
