Poisson's And Laplace's Equation

Poisson's And Laplace's Equation

The electric potential of the system can be calculated by relating it to the electric charge densities that give rise to the electric potential. The differential form of Gauss's law expresses the electric field's divergence in terms of the electric charge density.

Background:

Surface plasmon polaritons (SPPs) are electromagnetic waves coupled to electron oscillations at metal-dielectric interfaces.
Long-range SPPs are crucial for nanoscale optical devices but their behavior in complex structures requires detailed study.

Purpose of the Study:

To develop and validate a computational method for simulating long-range SPP modes in plasmonic transmission lines.
To investigate the influence of structural parameters on SPP propagation characteristics.

Main Methods:

Numerical simulations of planar metal-dielectric structures using eigenfrequency analysis.
Application of mixed periodic, electric, and magnetic boundary conditions.
Validation against the semi-analytical method-of-lines.

Main Results:

Accurate simulation of long-range SPP modes in plasmonic transmission lines.
Analysis of the trade-off between SPP mode confinement and propagation distance.
Modeling of SPP behavior in bent waveguides and in the presence of disorder and periodicity.

Conclusions:

The developed computational method provides a reliable tool for studying long-range SPPs.
Understanding these modes is key for designing advanced plasmonic devices with tailored properties.
