Abstract

A device (201) is provided for dispersing microwave radiation during microwave oven heating comprising a dielectric substrate (202), a reflective material (203) configured to reflect incident microwave radiation, said reflective material formed on said substrate and raised portions (205). The raised portions are configured to disperse microwave radiation, thereby reducing constructive or destructive interference of microwaves which give rise to hot-spots during microwave oven heating, and heating foodstuffs in the microwave oven more easily.
