Geometrical Optics:
An Electromagnetic Twist
Integrating geometrical optics into a multiscale simulation and design framework necessitates a
more comprehensive understanding of geometrical optics, extending beyond the traditional ray tracing paradigm.
Geometrical Optics for Electromagnetic Fields
In a multiscale simulation framework, geometric simulation models must be grounded in a geometric theory for electromagnetic fields. While the concept of geometrical optics for electromagnetic fields might appear outlandish, it was already proposed by Max Born and Emil Wolf in their famous work, Principles of Optics.
Ray tracing is a particular configuration within geometric simulation models for electromagnetic fields.
Geometric Simulation Models for Electromagnetic Fields
Consequently, the creators of VirtualLab Fusion adhered to Born and Wolf’s suggestion, creating a geometric theory for electromagnetic fields. As a result, VirtualLab Fusion offers a geometrical optics simulation model for the propagation of electromagnetic fields through smooth surfaces, such as lens and freeform surfaces.
