The highlight of his research achievements.

He the Self-complementary antenna and
its constant-impedance property in 1948. The equation

which gives the value of the constant-impedance is called
Mushiake relationship. With the extensions of this concept to
other cases he creatively discovered a general principle, the
Principle of self-complementarity. His research group developed
various $B!H(Bextremely broadband antennas$B!I(B
as the application of this principle.

Also he proved the non-broadband property of
incorrectly arranged log-periodic antenna.

IEEE Milestone was dedicated to Tohoku University on the basis of his research achievements, on the day of 2017/7/27. IEEE $B%^%$%k%9%H!<%s$N@bL@(B
