This Special Issue of the IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES (TMTT) is comprised of expanded articles from the 2020 IEEE International Microwave Symposium (IEEE IMS) held virtually on August 4–6, 2020, in response to the worldwide COVID-19 pandemic. We thank the hard work of the IMS2020 executive and technical committees that helped to rapidly pivot from plans to hold a physical conference at the Los Angeles Convention Center to the first virtual IEEE IMS conference.

IEEE微波理论与技术交易（TMTT）的特刊包含了2020年IEEE国际微波专题讨论会（IEEE IMS）的扩展文章，这些主题实际上是在2020年8月4日至6日举行的，以应对全球COVID-19大流行。我们感谢IMS2020执行委员会和技术委员会的辛勤工作，这些工作帮助从计划在洛杉矶会议中心举行物理会议的计划迅速过渡到了第一届虚拟IEEE IMS会议。
