The underlying physics of a capacitively coupled plasma is rather complicated, even for rather simple geometric configurations and plasma chemistries. This model benchmarks the Capacitively Coupled Plasma physics interface against many different codes. Mehr lesen
This model of a circular waveguide demonstrates how to use ports with numerical solution of the port modes. It illustrates how to align the polarization of degenerate port modes and in particular how to model and excite the TE11 mode of circular waveguides in 3D. Mehr lesen
In this model, we show how to model Seebeck effect which works as a thermoelectric generator. Seebeck effect is a phenomena where the difference in temperature of a material leads to a potential difference. The potential drawn in this model was compared with the paper by Jaegle (Example ...

Squeezed-film gas damping is a critical aspect of many MEMS transducers and actuators. In accelerometers, for example, inertia produces a motion that the device detects. A typical structure connects a large proof mass to surrounding structures with elastic beams, which forms a mechanical ... Mehr lesen
This tutorial model demonstrates how to compute the impedance of a capacitively coupled plasma. The Time Periodic study computes the time periodic solution of the plasma. Subsequently, the solution is transformed to the time domain, after which the fast Fourier transform (FFT) solver is ... Mehr lesen
This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... Mehr lesen
These two models show how to set up a magnetohydrodynamics model using either a fully coupled approach, or a one-way coupled approach. A more detailed description of these models can be seen in the blog post "Building a Magnetohydrodynamic Multiphysics Model in COMSOL®". Mehr lesen
A Touchstone file describes the frequency responses of an n-port network circuit in terms of S-parameters. This can be used to simplify arbitrarily complex circuits. The Touchstone file can be obtained from numerical simulations or network analyzer measurements. The obtained file for a ... Mehr lesen
In a diode or a transistor, when a p-n junction is reverse-biased (the p-side is connected to a lower potential than the n-side), ideally, no current should flow. However, due to minority carriers (electrons in the p-side and holes in the n-side), a small current, known as the reverse ... Mehr lesen
The double barrier structure is of interest because of its application in semiconductor devices such as resonant-tunneling diodes. This verification example demonstrates the Schrödinger Equation interface to set up a simple 1D GaAs/AlGaAs double barrier structure to analyze the ... Mehr lesen
