Abstract:
A method for ensuring a more uniform heating of food by microwaves comprising:providing food in a portion having a predetermined size and shape; providing a container adapted for receiving and reheating the portion of food in a microwave oven; wherein the container includes a supporting cavity consisting of peripheral sides and a bottom side, with the peripheral sides of the container being circumferentially shielded by a microwave reflective material such that the microwave reflective material on the peripheral sides forms a circumference having axial and transverse distances that are determined so as to change the wavelength of resonant modes in the supporting cavity; wherein the microwave reflective material is configured as a band and is positioned to allow microwaves to enter the cavity and to avoid non-heated areas in the cavity by arranging the food lower surface contacting the bottom side to be placed at the lower line of the band of reflective material or at a level above it by up to 10 mm; placing the portion of food in the supporting cavity; and heating the food and container with microwaves so as to expose the food to the changed wavelengths of resonant modes in the cavity thereby resulting in a more uniform heating food pattern and a more uniform heating of the food.
