Document Type and Number:
WIPO Patent Application WO/2012/087870
Kind Code:

Abstract:
An optimized microwave barrier assembly for use in conjunction with a microwave wood heater. The barrier is configured to allow microwaves to pass therethrough in a TMab) mode, where a is 0 and b is an integer between 1 and 5. The barrier assembly is also configured to maintain a pressure differential across a window of the barrier assembly. Such a configuration can reduce or eliminate arcing in the barrier assembly, even at low pressures.
