The Design Module includes these features, plus the following 3D CAD operations: loft, fillet, chamfer, midsurface, and thicken. Sometimes, modes have a very small propagation constant (close to zero) and a small effective index. The parameter estimation method is based on least-squares fitting and can be used when the reference data is a function of time or a single parameter. To set up a parameter optimization in COMSOLMultiphysics, you only need to add a general-purpose Optimization study. Creating an app for this task packages the complexity of this process into a custom user interface, allowing various users to run optimal control simulations simply by specifying their desired outputs. In any model that is used for simulating electromagnetic motion, you can examine the rigid or flexible body dynamics under the influence of magnetic forces and torques, induced currents, and mechanical load and spring configurations.

Using a Numeric Port implies that the mode profile and its propagation constant will be calculated during the Boundary Mode Analysis study step, which is almost identical to Mode Analysis. Many mode swaps are visible, e.g., there are shifts of Ey11 and Ex11 around w_core*ewfd.k0 = 2 and of Ey21 and Ex21 around w_core*ewfd.k0 = 3.5. However, trying to design experiments that allow you to extract the desired parameters with analytical methods can be challenging. For radiofrequency models, you will usually need electrical conductivity, relative permittivity, and relative permeability. For wave optics models, you will usually need a refractive index. By default, the software uses five elements per wavelength for each material. Using apps also offers a more efficient workflow for optimal control. An associated settings window prompts you to add an objective function, control variables and parameters, and constraints. You also have several global variables based on eigenvalue lambda for each mode, including the propagation constant, attenuation constant, and effective mode index.
