This introduction model creates a simple model of the electrostatics problem with two concentric cylinders of infinite length, which is commonly found in textbooks. Since there is an analytical solution to this problem, the model can be used to compare theory with numerical results from ... 詳細を見る
The dielectric shielding boundary condition is meant to approximate a thin layer of material with high relative permittivity compared to its surroundings. This boundary condition is available for electrostatic field modeling. This example compares the dielectric shielding boundary ... 詳細を見る
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. 詳細を見る
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and ... 詳細を見る
This model uses the Semiconductor and RF modules to describe a photoconductive antenna (PCA). A laser pulse is applied on the surface of undoped LT-GaAs to generate electron-hole-pairs, which move under the influence of an external E-field creating a transient electric current pulse. ... 詳細を見る
This model shows how to add several linked mobility models to the simple MOSFET example. 詳細を見る
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. 詳細を見る
This tutorial model explains how to extract lumped matrices by means of the Stationary Source Sweep study. The capacitance matrix of a five-terminal system is used to infer the position of a metallic object rather like real-world capacitive position sensors. The example illustrates the ... 詳細を見る
A homopolar generator is composed of an electrically conductive rotating disc placed in a uniform magnetic field that is perpendicular to the plane of rotation. The motion of the conductor through the static magnetic field induces Lorentz currents in the disc. By connecting the outside ... 詳細を見る
A parallel wire transmission line is composed of two conducting wires in a dielectric such as air. The fields around such a transmission line are not directly confined by the conductors, and extend to infinity, although they drop off in rapidly away from the wires. This model ... 詳細を見る
