Definition

The finite-difference frequency-domain technique is a numerical technique for the solution of Maxwell’s equations of electromagnetism in the frequency domain. It is based on approximating the derivatives in Maxwell’s equations by finite differences, and results in a system of algebraic equations, which is solved using numerical linear algebra techniques.

Introduction to the Simulation of Plasmonic Devices

The finite-difference frequency-domain (FDFD) technique is a general-purpose numerical technique for the solution of Maxwell’s equations of electromagnetism in the frequency domain. It can be applied to structures of any length scale and for sources of electromagnetic radiation of any frequency. Here, however, the focus is on the use of this technique in nano-optics, and in particular plasmonics.

Plasmonics is a rapidly evolving field of science and technology based on surface plasmons, which are electromagnetic waves that propagate along the interface of a metal and a...
