This example provides a walkthrough on how to simulate the basic radiated emission of a printed circuit board and its immunity response from outside noise. First, when one of the microstrip lines is excited, the crosstalk to an adjacent printed line and the radiated field, through an ... 詳細を見る

This model demonstrates the switching capability of a liquid crystal (LC) display cell in In-Plane Switching (IPS) configuration. The Oseen-Frank model is used to solve for the LC director (optical axis) distribution when a static electric field is applied. A Weak Form PDE interface is ... 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 model analyzes the operation of a micromirror in air and the effects of thermoviscous damping on the vibration response. The model includes thermal losses in the structure as well as thermoviscous acoustic phenomena. The model couples the Thermoelasticity multiphysics interface to ... 詳細を見る

An eigenfrequency study is used to find the resonance frequency and threshold gain for an oxide-confined, GaAs-based, vertical-cavity surface-emitting laser (VCSEL). The simulations are performed in two steps. A regular eigenfrequency analysis is first performed, to find good initial ... 詳細を見る

Developments in the last decade have made circuit quantum electrodynamics (cQED) the leading architecture for quantum computation. cQED is the solid-state version of cavity QED, which studies the basic light-matter interactions at the quantum level. This model examines one of the main ... 詳細を見る

This tutorial demonstrate the use of a Cross Grating feature in an échelle spectrograph. A cross grating is a periodic surface with two directions of periodicity. In this model the cross grating is used in high order in one direction and in first order in the orthogonal ("cross") ... 詳細を見る

この例では, 静電インターフェースを使用して, 一般的な高電圧絶縁体の表面電場を計算する方法を示します. グレーディングリングを設置すると, 表面電場の不均一性と最大値が大幅に減少することが示されています. このようにして, 高電圧絶縁体はより高い過電圧に耐えることができます. 詳細を見る
