Magnetron with slit anode:
1) cathode, 2) anodes,
3) permanent magnets

Okabe developed the magnetron with a slit anode or slot anode, which enabled a system with microwave length and laid the foundations for the development of the radar system. His work on several types of magnetrons had a profound impact on developments in this area around the world. After the Pacific War he worked on ultrasound techniques in the medical field.

In 1936 Okabe received the Asahi Prize , in 1941 the Onshishō Prize (恩賜 賞) of the Academy of Sciences followed , in 1944 Okabe was awarded the Order of Culture and subsequently honored in 1951 as a person with special cultural merits .

Remarks

  1. ↑ Since the imperial cultural order may not be linked to a payment, the distinction "person with special cultural merits" was introduced in 1951, which is linked to an honorary salary from budget funds. Only some of those who have been honored receive the cultural medal at the same time or later.
