This tutorial explains all the steps to simulate the 2-dimensional beam splitter problem using Electromagnetic Waves Frequency Domain physics in COMSOL Multiphysics.
This video includes:
1- Problem definition (Problem statement)
2- Selecting 2D space dimension
3- Importing parameters from the text file
4- Building 2D beam splitter in COMSOL
5- Assignment of material (Glass quartz) from the library
6- Selecting EMFD physics and assignment of boundary conditions
7- Scattering boundary conditions: (a) Incident gaussian beam (b) transparent boundaries (c) transition boundary condition (silver)
8- Generating Mesh
9- Selecting appropriate study (Frequency domain)
10- Computation and post-processing results in COMSOL (2D surface plots)
