More flexibility has been added to the Electromagnetic Waves, Beam Envelopes physics interface by way of a new section in the Settings window called User Defined Wave Vector Specification. The electric field, the reflectance and transmittance, and the refractive index profiles can be displayed in the graphics window, in addition to the geometry and the mesh.

Parameter sweeps over the wavelength or the spot radius can be performed. The graphics window to the right displays the beam, incident from the left, that is reflected upwards by the thin-film stack applied to the boundaries between two prisms. Screenshot of the Polarizing Beam Splitter app. Wave_Optics_Module/Applications/polarizing_beam_splitter Also presented is the reflectance and transmittance. The app displays the norm of the total electric field and the electric field for the first and second wave for a given wavelength or spot radius and polarization. Sweeps can be performed over a range of wavelengths or spot radii. You can enter refractive indices for the prisms and the layers in the dielectric stack, either directly or through a predefined material list. This new app demonstrates the basic MacNeille design, which consists of pairs of layers with alternating high and low refractive indices, and where you can select how many layers will make up your splitter. An advantage of using this cube design, instead of a plate design, for beam splitters is that ghost images are avoided. The cube transmits part of the incident wave while reflecting the other part. Polarizing beam splitter cubes consist of two right-angled prisms where a dielectric coating is applied to the intermediate surface.

Different frequency-domain interfaces can be coupled with the new Polarization domain feature.
