Abstract

An optimized microwave barrier assembly suitable for use with a vacuum microwave heater. The barrier assembly is configured to allow microwaves to pass therethrough in a TMab mode, wherein a is 0 and b is an integer in the range of 1 to 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.
