Abstract
A microwave energy heating element has a plurality of spaced microwave components generally arranged in a closed loop pattern. Each of the microwave components (42, 44) has a non-resonant length. When the heating element is in a loaded condition with a load juxtaposed thereto for capacitively coupling the microwave components together, the microwave components cooperatively redistribute impinging microwave energy. When the heating element is in an unloaded condition, the microwave components act independently remaining inert to impinging microwave energy.

A microwave energy heating element comprising a plurality of spaced microwave components generally arranged in a closed loop pattern, each of said microwave components having a non-resonant length, and when in a loaded condition with a load for capacitively coupling said microwave components together, said microwave components cooperatively redistribute impinging microwave energy, and when in an unloaded condition, said microwave components act independently remaining inert to impinging microwave energy.
A sandwich coupon comprising
- a substrate;
- a plurality of spaced microwave components generally arranged in a closed loop pattern on said substrate, each of said microwave components having a non-resonant length, and when in a loaded condition with a load for capacitively coupling said microwave components together, said microwave components cooperatively redistribute impinging microwave energy, and when in an unloaded condition, said microwave components act independently remaining inert to impinging microwave energy.
A microwave energy heating element comprising a continuous portion having a non-resonant length and a discontinuous portion comprising a plurality of spaced microwave components, each of said microwave components having a non-resonant length, when said heating element is in a loaded condition with a load for capacitively coupling said continuous portion and said discontinuous portion together, said heating element cooperatively redistributes impinging microwave energy, and when in an unloaded condition, said continuous and discontinuous portions act independently remaining inert to impinging microwave energy.
