To facilitate the exchange of ideas among different research areas within the Program and to improve students’ oral presentation skills, the PhD in Computer Applied Technology Program organizes regular PhD student seminars. Recently, a PhD Student Seminar, entitled “Reconfigurable Intelligent Surface for 6G Communications”, was held at the School of Applied Sciences in Macao Polytechnic Institute. The talk focused on the introduction to the emerging research area in reconfigurable intelligent surface (IRS) and its application in high mobility scenario. He also discussed his future research directions.
