Abstract
For improving a stabilizing efficiency of neoclassical tearing modes, the new type diplexer as a fast switching device of high power millimeter wave is proposed for an electron cyclotron current driving system. The principle is a ring resonator-type switch consisting of a ring corrugated circular waveguide, a pair of mitre-bends, and a pair of half mirrors. A mock-up diplexer was designed, fabricated, and tested in low power. The switching operation of the mock-up diplexer with slotted metal half mirrors was verified at the frequency bands of 137 GHz and 170 GHz.
