Time-Domain Modeling of Dispersive Drude–Lorentz Media (Wave Optics)
Application ID: 22281
This tutorial shows how to solve the full time-dependent wave equation in dispersive media such as plasmas and semiconductors. The 2D TM in-plane wave model solves for the vector potential from the wave equation and for an auxiliary electric polarization density from an ordinary differential equation.
The geometry consists of a single dispersive slab with a sub-wavelength slit in it. Periodic boundary conditions are applied, thus physically this is an array of slits. The source of electromagnetic radiation is a plane wave pulse with flat front and Gaussian temporal shape.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the 製品仕様一覧 and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
