A Gaussian electromagnetic wave is incident on a dense array of very thin wires (or rods). The distance between the rods and, thus, the rod diameter is much smaller than the wavelength. Under these circumstances, the rod array does not function as a diffraction grating (see the Plasmonic ... Mehr lesen
A gate-all-around MOSFET consists of a nanowire with a gate electrode wrapped around the circumference. Since the entire nanowire forms the channel, this configuration provides the best possible electrostatic control of the channel and offers a good candidate for the miniaturization of ... Mehr lesen
In this model, two fluids are separated by a solid elastic structure. An acoustic pressure wave impacts the structure resulting in a reflected wave and a wave transmitted with a loss through the structure. This model investigates the transmission loss through the structure. The effects ... Mehr lesen
Ultraschall-Durchflussmesser bestimmen die Geschwindigkeit eines Fluids, das durch ein Rohr fließt, indem sie ein Ultraschallsignal in einem schrägen Winkel durch die Strömung senden. Wenn keine Strömung vorhanden ist, ist die Übertragungszeit zwischen dem Sender und dem Empfänger für ... Mehr lesen
This is a 2D model of an anisotropic porous absorbing material. The absorption coefficient alpha are determined as functions of frequency for three different incidence angles. The example uses Periodic Floquet boundary conditions. The model uses two different methods for modeling the ... Mehr lesen
The primary defense of a submarine lies in its capacity to remain hidden during operation. As radio waves are strongly absorbed by sea water, sound navigation ranging, or SONAR, is one of the main methods used for the detection of submarines. SONAR systems are also used for underwater ...

This tutorial shows how to model a miniaturized magnetostrictive antenna developed for use inside living cells. The stress in the antenna, the magnetic flux density, the current density, and the displacement of the tip of the device are investigated at the resonance frequency. Mehr lesen
This tutorial model demonstrates the use of the multiphysics coupling feature Thermal Connection, Layered Shell, Edges. In this model, three layered shells are connected to heat domains by edges at difference locations related to the heat domains. The results obtained with the Heat ... Mehr lesen
The problem of a plane wave scattering off a cylinder-shaped object suggests the use of the 2D axisymmetric formulation. This can save computation time and reduce the memory usage compared to the model in 3D space. This example demonstrates the use of the built-in plane wave expansion ... Mehr lesen
In this model, the scattering coefficient of a Schroeder diffuser is calculated. This coefficient can then be used as input to express boundary conditions in typical room acoustic simulations. The effect of periodicity is also investigated by studying the responses from different ... Mehr lesen
