MEMS scanning mirrors are a type of MEMS device that realizes optical path control by controlling mirror torsion through a microdriver. The torsion can be single axis or double axis. MEMS scanning mirrors are widely used in laser projection, laser radar, laser processing, and other ... Mehr lesen
A metallic cylindrical rod is hidden inside a spherical dielectric shell and its orientation is unknown. By studying the polarization-dependent scattered field of a cylindrical object and performing a parametric sweep as a function of polarization angle, the rod is detected for the ... Mehr lesen
A capacitive micromachined ultrasonic transducer (CMUT) is a micro-scale receiver that converts ultrasound to electrical signal for high-resolution imaging application. This CMUT design has optimized force-displacement characteristics for increased transduction efficiency. Central to the ... Mehr lesen
Superconducting materials have zero resistivity up to a certain critical current density, above which the resistivity increases rapidly. To model such a material, this example uses the Magnetic Field Formulation physics interface. The model was based on a suggestion by Dr. Roberto ... Mehr lesen
This tutorial model shows how to model a microspeaker located in a smart phone including the radiation through and interaction with the acoustic port that connects to the exterior. The model demonstrates a linear frequency domain analysis as well as a nonlinear time domain analysis. A ... Mehr lesen
This model solves the Boltzmann equation in two-term approximation for a mixture of nitrogen and oxygen representing a background gas of dry air. Electron transport coefficients and source terms are computed by suitable integration of the electron energy distribution function over ... Mehr lesen
Das Modell analysiert die Modenausbreitung in einem Nano-Schlitzwellenleiter. In einer Schlitzwellenleiterkonfiguration sind zwei Platten mit hohem Brechungsindex (~3,48) neben dem Schlitz mit niedrigem Brechungsindex (~1,44) angeordnet. Die Modenanalyse wurde an einem 2D-Querschnitt ... Mehr lesen
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... Mehr lesen
This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB ... Mehr lesen
The mutual inductance and induced currents between a single turn primary and twenty turn secondary coil in a concentric coplanar arrangement is computed using a frequency domain model. The secondary coil is modeled using a homogenized approach which does not explicitly consider each turn ... Mehr lesen
