This example demonstrates the usage of the Scattered Field formulation to compute the scattering of light off of a single scatterer on top of a dielectric half-space. It uses the analytic Fresnel equations to design the background field. For a detailed introduction to this model, see ... Mehr lesen
This model demonstrates how to tune the lowest natural frequency of the diaphragm of a MEMS microphone using Shape Optimization. The Stationary then Eigenfrequency study modifies the shape of the suspension springs that support the diaphragm. Although the model is in 3D, shape change is ... Mehr lesen
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... Mehr lesen
This model demonstrates two ways of modeling waveguides that support multiple modes. A PML can be used to absorb any modes, or Ports can be explicitly added for each possible mode. Learn more in this accompanying blog post: Modeling Waveguides that Support Multiple Modes Mehr lesen
This model simulates the initiation of streamers from suspended metal particles, their propagation under a high electric field, and their subsequent merging. The discharge current flows into the metal particles, which are maintained at equal potential. These suspended particles enhance ... Mehr lesen
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ... Mehr lesen
The model estimates the AC breakdown voltage between parallel electrodes in air by simulating charge transport dynamics. To keep computations efficient, it is implemented in one dimension, though it can be adapted for different gases and extended to higher-dimensional setups. The ... Mehr lesen
Creating irregular geometries can be a good solution, even the only option, for some types of applications. These files present a way to use a text file with material properties defined in coordinates to assign different materials even though there is only one regular domain. The same ... Mehr lesen
This model demonstrates a technique for partitioning a mesh based upon the element type. By first meshing with a boundary layer and then partitioning and creating a new mesh, it is possible to avoid modeling the interior volume of inductively heated parts, where the skin depth is small ...
