This tutorial demonstrates how to build the geometry for the 3D biased resonator from GDS file using the ECAD Import Module and the Design Module. The procedure emulates semiconductor and MEMS fabrication processes to build 3D geometry more efficiently and is more intuitive for those ... En savoir plus
This example uses asymptotic techniques to study the radar cross-section (RCS) response of a conductive sphere. The selected physics interface transforms the incident plane-wave field on the boundaries to the far-field using the Stratton–Chu formula. The computed results are compared to ... En savoir plus
This example shows an approximate approach to model a dot-in-well solar cell as described by Asahi et al. in the reference paper. The quantum wells and the layers of quantum dots are each treated as lumped energy levels in the band gap. The authors specify transitions between the dot ... En savoir plus
Many applications involve simulating the electromagnetic behavior of relatively thin material in voluminous domains. To save computer memory and processing time, the thin materials can be treated differently by resolving them with 3D meshes. Here, the modeling domain is a box filled ... En savoir plus
Breaker and disconnector devices are widely used in AC substations in power systems.In this model, the Electrostatics Interface is used to simulate the electric potential and electric field in a 110kV 3-phase high-voltage switchgear operating at 50 Hz. A surrogate model is also trained ... En savoir plus
This model demonstrates how to use topology optimization with milling constraints to design a metalens that focuses a single wavelength to a point. This involves transferring the optimized results to another component so the result can be verified using an explicit geometry ... En savoir plus
In this example, an SF6/argon plasma reactor at moderate pressure is studied using a global model. The heavy species heat equation is included. Parametric sweeps for input power and argon mole fraction are computed. En savoir plus
Combinations of optical devices such as polarizers and wave retarders can be used to control the intensity and polarization of transmitted radiation. In this tutorial, two linear polarizers with orthogonal transmission axes are used to reduce the intensity of a ray to zero. Then the ... En savoir plus
Electron transport in low-temperature plasmas depends strongly on the electron energy distribution function (EEDF), which is often approximated as Maxwellian but is frequently nonequilibrium in reality. Incorporating nonequilibrium EEDF behavior into spatially dependent models often ... En savoir plus
The metal-silicon-oxide (MOS) structure is the fundamental building block for many silicon planar devices. Its capacitance measurements provide a wealth of insight into the working principles of such devices. This tutorial constructs a simple 1D model of a MOS capacitor (MOSCAP). Both ... En savoir plus
