Electromagnetic scattering simulation for an object with continuous rotational symmetry can be performed in 2D axisymmetry instead of 3D to drastically reduce computational time and resources. This model shows how to simulate arbitrary plane wave incidence in 2D axisymmetric models by ... Mehr lesen
While transient analyses are useful for time domain reflectometry (TDR) to handle signal integrity (SI) problems, many RF and microwave examples are addressed using frequency domain simulations generating S-parameters. However, from the frequency domain data it is difficult to identify ... Mehr lesen

Extending the High Voltage Insulator model, this example shows how to set up an Optimization Study to determine the optimum position of the grading rings to obtain the highest flashover voltage. Mehr lesen
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 ... Mehr lesen
Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to ... Mehr lesen
This tutorial model solves for a one-dimensional capacitively coupled plasma reactor in a mixture of argon/oxygen. Important aspects and strategies for modeling electronegative discharges are discussed. Mehr lesen
Es ist bekannt, dass die Antwort einer Millimeterwelle mit Frequenzen von 35 GHz und 95 GHz sehr empfindlich auf den Wassergehalt reagiert. Dieses Modell nutzt eine 35-GHz-Ka-Band-Millimeterwelle mit geringer Leistung und ihre Reflektivität gegenüber Feuchtigkeit für die nichtinvasive ... Mehr lesen
This is a transient model of an electromagnetic plunger with stopper restricting the linear motion. The model consists of a magnetic core, nonmagnetic guider, multi-turn coil, nonmagnetic stopper/blocker, and magnetic plunger attached to the spring and damper at the base. The ... Mehr lesen
This example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ... Mehr lesen
