In 1919 the Department of Electrical Engineering (EE) was established in Tohoku University (at that time, Tohoku Imperial University). In this Department a growing tendency towards research featured in science and technology for electrical communication. Great efforts made in these fields produced pioneering studies such as those of the Yagi-Uda antenna and slotted-anode type magnetrons in the late 1920s. The purpose of this article is to introduce the history of development of microwave electron-tube at Tohoku University, which was started with the Okabe's magnetron.
