Total Internal Reflection
Application ID: 71841
The bidirectional formulation of the Beam Envelopes interface can be used not only for counter-propagating wave simulations but also for waves propagating to up to two directions.
In this model, an almost collimated Gaussian beam is excited at the left boundary and exhibits total internal reflection (TIR) at the interface of two media on the sides and gets out the domain from the right boundary at 20 mm away.
This is useful for virtual reality (VR) simulation.
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 Specification Chart 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.
