This project directed by Prof. Yin Wenyan in Department of Information Science and Electronics Engineering was supported as the key project by NSFC. It aims at developing accurate modeling techniques and efficient algorithms for handling multiphysics processes with mutual coupling in typical multi-scale heterogeneous structures in the presence of an electromagnetic excitation, in particular including flexible electronic devices and integrated circuits, flexible MEMS and advanced GaN microwave transceivers. Its research tasks and targets are outlined as follows.
Therefore, we are able to reveal the evolution of multiphysics processes at different scales in the above heterogeneous structures, also including physical mechanisms of their performance degradation, fatigue and even breakdown. It is believed that this research can provide some key techniques for supporting the development of new flexible electronic devices and circuits, flexible MEMS and high power GaN transistors with high reliability, and international competitiveness of China in these key areas will be enhanced.
