In memoriam: Tatsuo Itoh 1940–2021

Abstract

It is not easy to describe the shock and pain of our community after receiving the sad news of the passing of Prof. Tatsuo Itoh. It is so unfortunate that Prof. Itoh accepted giving an invited talk after the Covid-19 pandemic at GASS 2021. It is very hard to find anyone else who has contributed so much, so deeply, and inspired so many people in microwave engineering. Prof. Itoh continuously introduced revolutionary breakthroughs, one after another, until his passing. His gigantic work, remarkable for its quality and diversity, constitutes an extraordinary asset that will guide our explorations and investigations for decades to come. We express our endless recognition and respect for his legendary life and integrity. We express our deepest and sincere condolences to his family.
