On behalf of the ISEM 2023 Organizing Committee, we are honored to publish selected contributions presented at the 21st International Symposium on Applied Electromagnetics and Mechanics (ISEM 2023), which was held in November 2023 in Hachioji, Tokyo, Japan.

Since its inception in 1988 in Japan, ISEM has been held in various countries, including Korea, the United Kingdom, Germany, Italy, France, Austria, the United States, China, and Canada. Over the years, the symposium series has grown in scale, significance, and international recognition. We are privileged to continue this well-established tradition of presenting cutting-edge research and ideas in the field of applied electromagnetics and mechanics.

For ISEM 2023, a total of 236 papers were submitted to the editorial board, of which 227 were accepted for presentation and were included in the program. The authors represented 10 countries.

After a rigorous peer-review process, 50 of the 131 extended papers were accepted for publication in the International Journal of Applied Electromagnetics and Mechanics (IJAEM). For the volume in the book series Studies in Applied Electromagnetics and Mechanics, 41 extended papers were accepted for publication.

The success of ISEM 2023 was made possible through the dedicated efforts of many individuals. In particular, we would like to extend our deepest gratitude to the members of the local organizing committee, the staff of the Hachioji Convention and Visitors Association, who worked tirelessly to ensure the symposium’s success, and the ISEM International Steering Committee, chaired by Professor Toshiyuki Takagi, for their invaluable guidance and support.

We would also like to express our sincere appreciation to Antonello Tamburrino, Editor-in-Chief of IJAEM, and Gabriela Ricci, Associate Publisher at IOS Press, for their prompt assistance and unwavering support in facilitating the smooth publication of this special issue. Furthermore, we extend our heartfelt thanks to all our colleagues who contributed as reviewers.
