Recent propagation studies in Japan

Reviews activities in the field of propagation research, in the 1990s, in Japan. The authors focus only on propagation studies related to radio communications; activities in the field of remote sensing are outside the scope of this review. Since Kagoshima and Shiokawa (1992) included a short review of research activities in this field, in the period from 1989 to 1991, the emphasis of the present review is placed on activities after this period. The list of references consists of only papers written in English, which have appeared in international journals or published proceedings of international conferences. Reflecting the activities of various fields of propagation research in Japan, two-thirds of the review is devoted to propagation studies related to mobile communications, including land-mobile, mobile-satellite, and indoor communications. The rest of the review covers other basic studies, related to propagation through the atmosphere and precipitation.<>
