Surface micromachined thin films are often subject to residual stress. This COMSOL Multiphysics example describes a thin film resonator with straight or folded cantilever beam springs. The resonance frequencies of the resonator are affected by thermal stress. Using folded springs ... 詳細を見る

This model studies the heat conduction in a building structure separating two floors from the external environment. Four materials with distinct thermal conductivities k compose the structure. The exterior and interior boundaries are facing environments respectively at 0°C and 20°C. The ... 詳細を見る

This 3D model example demonstrates the use of the Primary Current Distribution interface for modeling current distributions in electrochemical cells. In primary current distribution, the potential losses due to electrode kinetics and mass transport are assumed to be negligible, and ... 詳細を見る

The first part of the application computes the modes for a straight step index fiber made of silica glass. In the second part, a step index fiber bend with a 3 mm radius of curvature is analyzed with respect to propagating modes and radiation loss. It is shown how to find the power ... 詳細を見る

This model addresses the concept of wireless power transfer by studying the energy coupling between two circular loop antennas tuned for UHF RFID frequency whose size is reduced using chip inductors. The circular loop antenna provides inherent inductive coupling by its shape, and it can ... 詳細を見る

This tutorial uses a 2D model of an acoustically driven microfluidic pump. The acoustic microfluidic pump is driven by acoustic streaming originating from sharp edges in the microfluidic channel. It drives a flow around a closed microfluidic channel loop. The acoustic field is modeled ... 詳細を見る

RF coils are important in numerous applications ranging from wireless technology to MRI scanning equipment. This introductory tutorial model demonstrates how to find the fundamental resonance frequency of an RF coil as well as how to perform a frequency sweep to extract the coil's Q ... 詳細を見る

In this first half of a two-part example, a 2D model of a trench-gate IGBT is built, which will be extended to 3D in the second half. In general, it is the most efficient to start with a 2D model to make sure everything works as expected, before extending it to 3D. The Caughey&ndash ... 詳細を見る

This example models time-dependent copper deposition on a resistive wafer in a cupplater reactor. As the deposited layer builds up, the resistive losses of the deposited layer decreases. The benefit of using a current thief for a more uniform deposit is demonstrated. 詳細を見る
