Patent ID: 8138458

Claim:
A microwave chemical reaction device comprising a first square waveguide for transmission of micro waves of TE10 mode, a first short circuit piece for short-circuit of a downstream end of said first square waveguide, a circular waveguide substantially at right angle connected at one end to said first square waveguide on an upstream side said first short-circuit piece, a second square waveguide substantially at right angle connected to the other end of said circular waveguide, a second short circuit piece connected at one end to said second waveguide near a junction of said circular waveguide, a non-reflective end piece for closing an end of said second waveguide opposite to said second short circuit piece and a micro-wave low-loss circular tube extending coaxially within said circular waveguide and accommodating reaction targets characterized in that TM01 mode microwave transduced from said TE10 mode microwave in said first square waveguide is transmitted into said circular waveguide and TE mode microwave re-transduced from said TM01 mode microwave within said circular waveguide is transmitted into said second square waveguide for consumption at said non-reflective end piece.
