Instructions for presenters

Oral presentation

Metamaterials 2021 will be run virtually, through the Zoom web Conferencing Platform. Basic instructions about this platform can be found here. You can choose to either present your talk live during the session or to send a pre-recorded video of you talk (with deadline September, 6) that will be played during the live session by the Session manager. Please note that if none of these options will be used, the paper will be considered as “no-show” and will not be published in the Conference proceedings.

We also encourage you to post a poster summary of your paper on Twitter using the tagline #mtm2021NYC, starting one week before the conference.

Live talk

If you opt for the live presentation, you have to join your session at least 15 minutes early of the assigned time-slot using the dedicated link. When it is your turn, you should present your talk as in a physical meeting conference. Each session will proceed in the order identified, maintaining the schedule. As in a regular meeting, each talk will be comprised of a presentation and subsequent, dedicated Q&A. The session manager will read questions submitted by participants to the speaker. The maximum talk duration (Q&A included) is 15 minutes for regular talk and 30 minutes for invited presentation.

In preparation for the meeting, if you are not familiar with the platform please download the test via Zoom Test (https://zoom.us/test).  For the best experience, please use your webcam and test your audio. Please note that you have to “Share” your screen during the presentation and keep the webcam on so that attendees can view you during your presentation.
