The capability to alter the polarization of light is crucial to a wide variety of optical devices. For example, the polarization of light has a significant effect on the performance of optical isolators, attenuators, and beam splitters. By assigning a specific polarization to light, most ... 詳細を見る

This model shows how to analyze a tuning fork based piezoelectric rate gyroscope. The reverse piezoelectric effect is used to drive an in-plane tuning fork mode. This mode is coupled to an out of plane mode by the Coriolis force and the resulting out of plane motion is sensed by the ... 詳細を見る

This example model calculates the bistatic radar cross section (RCS) per unit length of a circle using the Electromagnetic Waves, Time Explicit physics interface. A 2D circle is excited by a 200 MHz sinusoidal signal modulated by a temporal Gaussian pulse. A wideband RCS frequency ... 詳細を見る

Microlaboratories for biochemical applications often require rapid mixing of different fluid streams. At the microscale, flow is usually highly ordered laminar flow, and the lack of turbulence makes diffusion the primary mechanism for mixing. While diffusional mixing of small ... 詳細を見る

When electrons are emitted from a heated cathode in a plane parallel vacuum diode, they contribute to the space charge density in the diode, which in turn affects the electric potential distribution. If the potential difference between the cathode and the anode is not sufficiently large, ... 詳細を見る

In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material. The generated voltage in windings around the stator is calculated as a function of time. COMSOL Multiphysics models the rotation with assemblies and ... 詳細を見る

This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. 詳細を見る

This tutorial shows how to model the propagation of acoustic waves in large pipe systems by coupling the Pipe Acoustics interface to the Pressure Acoustics interface. The tutorial is set up in both the time domain and the frequency domain. 1D pipe acoustics is used to model the ... 詳細を見る

The mutual inductance between a primary and secondary single turn coil in a concentric coplanar arrangement is computed using a DC, steady-state, model and compared against the analytic solution. The induced currents in the secondary coil are computed using an AC, frequency-domain, ... 詳細を見る
