COMSOL in electrochemical applications

Shuo-Jen Lee [1]
[1]College of Engineering, Yuan Ze University, Taoyuan, Taiwan

Microstructures such as holes, grooves, microchannels, and surface texture are essential geometric profiles for micro-components. Burs can cause interference, affect the positioning of processing, and influence the quality and surface appearance of the structure. Electrochemical ... 詳細を見る

Temperature Compensated AIN Based SAW Simulation using COMSOL
