ICEMP is an annual research conference aiming to provide a platform for the scientists, scholars, engineers and students from the Universities all around the world and the industry to present ongoing research activities. 2020 The 9th International Conference on Engineering Mathematics and Physics (ICEMP 2020) was held on July 1-4, 2020.This year, due to the instability of COVID-19 and travel restrictions from governments all over the world, ICEMP organizing committee held the conference as remote meeting. Though the authors and speakers couldn’t communicate face to face, the passion for involvement wasn’t affected. The conference was held virtually for 4 days including the online test on the first day, Keynote / Invited speeches on the second day and author parallel sessions on the last two days. Presenters made their presentations on the topics of Applied Mathematics, Engineering Physics and Mathematics, Advanced Mathematics and Engineering Applications. Every presentation was about 15 minutes including 2-3 minutes for Q&A part.ICEMP used ZOOM as the platform holding online conference. Because there are some emergencies and limitations existing, Organizing Committee made many preparations to hold ICEMP successfully. For example, some authors may have problem with the internet access, ICEMP collected back-up presentation videos in advance so that the staff could help to display when the internet on author’s side was not stable. The test session was also arranged to help authors learn some ZOOM basic functions. In addition, to provide a high-quality conference experience and to prevent technical problem, back-up room was also open every day during conference in case that some authors had questions.The proceedings present a selection from papers submitted to the conference from universities, research institutes and industries. All the papers were double-blind reviewed. 12 papers were accepted from 23 submissions to be collected in the conference proceedings-Journal of Physics: Conference Series. Here we would like to thank all the technical program committee members who made great efforts on paper reviewing.The appreciation also goes to other conference committee members, keynote/invited speakers, session chairs and all the authors, thanks for their understanding and support in this special time. Hope all the participants had wonderful time during conference and got fruitful inspirations from the presentations delivered by speakers and authors.Because of limitations on time zone and internet, there were still something regrettable. We are looking forward to seeing you again in ICEMP next year and we truly believe ICEMP will be better and better!
