Ein Mach-Zehnder-Modulator wird zur Steuerung der Amplitude einer optischen Welle verwendet. Der Eingangswellenleiter wird in zwei Wellenleiter-Interferometerarme aufgeteilt. Wenn eine Spannung an einen der Arme angelegt wird, wird eine Phasenverschiebung für die Welle, die durch diesen ... Mehr lesen
This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations ... Mehr lesen
This version of the balloon inflation example demonstrates how the Shell and Membrane interfaces can be used to model thin structures made of hyperelastic materials. The example is identical to the Model Library model 'Inflation of a spherical rubber balloon', except that the Membrane ... Mehr lesen
Conical antennas are useful for many applications due to their broadband characteristics and relative simplicity. In this example, we study the antenna impedance and radiation pattern as functions of frequency for a monoconical antenna with a finite ground plane and a 50 ohm coaxial ... Mehr lesen
In this tutorial model, the far-field radiation pattern of a dipole antenna is computed in a 2D axisymmetric model component. Then, in a separate 3D model component, a ray is released using the far-field radiation pattern to initialize the ray's intensity, polarization, and phase. Mehr lesen
This is a model of an RF waveguide bend with a dielectric block inside. There are electromagnetic losses in the block as well as on the waveguide walls which cause the assembly to heat up over time. The material properties of the block are functions of temperature. The transient thermal ... Mehr lesen
This app demonstrates the following: Creating apps for small screens such as smartphones User-interface navigation with a top menu typically used on websites Dynamically hiding forms using card stacks to minimize the space required by the app Changing appearance by using different ... Mehr lesen
The common electroanalytical method of exhaustive amperometric detection in a microscopic thin layer is modelled as a 1D-symmetric diffusion problem. The simulated result agrees with the analytical Cottrell equation at short times, and deviates as expected at long times when the ... Mehr lesen
This 2D axisymmetric model demonstrates the operation of a pyroelectric detector found in instruments for measuring laser energy. A disk of lithium niobate (LiNbO3) is sandwiched between two electrodes and connected to an external circuit. The disk is mounted on a ring-shaped ... Mehr lesen
Crystallization is an important separation process in the chemical industry. It is used for the production of pharmaceuticals and industrial chemicals. It can also be used in resource recovery as a way of separating valuable materials from waste. This model solves a discretized ... Mehr lesen
