Paper Submission

To encourage timely reporting of the latest results and have better opportunities to expand papers for possible journal publications, prospective authors are invited to submit a 3-page manuscript (both initial submission and final manuscript, if accepted) in English and in IEEE PDF eXpress format. The manuscript should emphasize original contributions and key findings, including figures, diagrams and results from both simulations and measurements. References should be clearly cited and up-to-date. Accepted conference papers can be submitted for inclusion into IEEE Xplore subject to meeting IEEE Xplore's scope and quality requirements. By submitting a manuscript, the authors agree that, if accepted, at least one of the authors will make a full registration and attend the RFIT2025 to present their paper.  All must be made through the RFIT2025 website: www.rfit2025.org

Author Instructions

Initial paper submissions
It is requested that authors submit an English, A4-size THREE-page preliminary paper based on the IEEE conference word or LaTeX templates. Papers should be uploaded in PDF format. It is imperative to note that all submitted papers will undergo a peer-review process. The Technical Programme Committee (TPC) will make the final decision, and accepted papers will be designated as either oral or poster presentations.

Final paper submissions
Authors should check PDF compatibility at IEEE PDF eXpress before submission. (Details for the PDF check compatibility will be provided soon) Final papers should be up to three pagers in English. Final papers will be uploaded to IEEE Xplore if their authors will be presenting at the conference.

Submission Policies
IEEE mandates that authors submit original work that has neither been published elsewhere nor is under review for another publication. Authors are required to disclose any prior publications and current submissions when submitting an article. This ensures the integrity of the publication process and avoids issues related to multiple submissions or prior publication.

Conference Events

Future engineers —Get Together—

We welcome high school students from the local area who are interested in the fields of microwaves and semiconductors. Graduate or undergraduate students will guide them to attend technical sessions and poster sessions. High school students, assisted by university students, will participate in technical session/poster session and discussion with presenters. In addition, high school students will be invited to a lunch meeting where they can interact with engineers and researchers working on a global scale. This activity will take place at the 2025 IEEE International Symposium on Radio-Frequency Integration Technology.

We are inviting students from the "Super Science High School" in the Kagoshima area, which is recognized by the Japanese government. This event will be supported by TC-9 and Kagoshima Prefectural Board of Education.

Schedule
1000–1100 Poster session
1100–1200 Interaction with graduate/undergraduate students
1200–1300 Lunch meeting with world class engineers/researchers
1500–1600 Poster session
