Abstract Submission Deadline: February 18, 2024 

Update: the abstract submission deadline has been extended to February 25, 2024

Author notification by email:  April 1, 2024
Information for Authors : Please see this page.

Authors whose papers have been accepted, will receive further instructions in the acceptance notification email. The deadline for proceedings paper submission is June 23, 2024.

Papers not presented during the Conference will be removed from the final proceedings.

All submissions must be made through the submission site epapers. A link to the submission site is now available on this page. The abstract shall be uploaded in PDF format via the submission portal. Complete submission guidelines for authors will also be available on the epapers site. During the submission process authors will be asked to indicate the preferred topic category, presentation format (oral, poster) and if the submitted work should be considered for the student poster competition.


On Monday, June 24 2024, there will be a series of tutorials covering a wide range of related topics. The tutorials include both the fundamental topics of frequency and timing at a level suitable for practitioners new to the field, and more advanced and specialized topics related to specific areas. As such, the tutorials aim to provide useful knowledge to the beginners in the community, as well as those with extensive experience. Detailed information will be posted on the conference web site as they become available.

Student Poster Competition

Students submitting abstracts for presentation are invited to participate in a student poster competition. To participate, the student must be the lead author and present the poster. If the paper is selected for oral presentation, the student must also provide a poster to participate in the competition. Winners will receive an award and a certificate. Further information will be available on the conference web site. Student authors selected for the student poster competition will be given preference for travel support. A request to be considered for the student poster competition must be made at the time of abstract submission.


A technical exhibition will be held in parallel to the conference. Please refer for details on www.eftf2024.ch or send an email to exhibition@eftf2024.ch
