Abstract: A radio frequency heating apparatus (100) having a cooking cavity (112) dividable into at least two sub-cavities (116, 118), a removable partition (114) for thermally insulating the at least two sub-cavities (116, 118), a rail (128) provided along a boundary of the cavity (112) for supporting the removable partition (114), and at least one radio frequency generator configured to transmit radio frequency radiation into at least one of the at least two sub-cavities (116, 118). The rail (128) is corrugated with a set of grooves or ridges (138), and a perimeter of the partition (114) is corrugated with a set of grooves or ridges (136) complementary to the grooves or ridges (138) of the rail (128).

Abstract: A transition device for a hollow waveguide comprises a rectangular structure comprising an inlet wall and interior extending from the inlet wall along a longitudinal axis. The inlet wall is configured to receive a transmission line comprising an antenna. The antenna forms a proximal end proximate to the inlet wall and a distal end configured to extend into the rectangular structure of the hollow waveguide. A channel is formed in the rectangular structure. The channel comprises a base forming a tuning surface. The tuning surface is configured to extend along a length of the antenna in a spaced configuration parallel to the longitudinal axis.

Abstract: A method for diagnosing an electromagnetic cooking device includes selecting a frequency from a set of frequencies in a bandwidth of radio frequency electromagnetic waves; setting a subset of a set of radio frequency feeds to output a radio frequency signal of the selected frequency; measuring a forward power level for the subset of the set of radio frequency feeds that is outputting the radio frequency signal; measuring a forward and backward power level for the set of radio frequency feeds; and processing the measurements of the forward and backward power levels to determine an operating condition of the electromagnetic cooking device based on the processing of the measurements of the forward and backward power levels.

Abstract: The microwave heating apparatus (100) comprises a cavity (101) arranged to receive a load (102A, 102B), at least two patch antennas (103A, 103B) coupled to the at least one microwave generator (104), and a control unit (105). Each of the at least two patch antennas (103A, 103B) is configured to radiate microwaves into a predefined direct heating zone (108A, 108B) within the cavity proximate the respective patch antenna (103A, 103B). The control unit (105) is configured to select energy levels for each of the at least two patch antennas (103A, 103B) as if the load (102A, 102B) were static and as if there not interference between the at least two patch antennas (103A, 103B).

Abstract: A method of determining heating strategies for a cooking appliance (10) includes obtaining geometry dimensions, power values, and frequency values of the cooking appliance (10), selecting a food item (14) and obtaining a food geometry, permittivity value, and initial temperature of the selected food item (14). A heating pattern (28) for heating the selected food item (14) is estimated based on the food geometry, permittivity value, and initial temperature of the selected food item (14) and data indicative of the estimated heating pattern (28) is inputted to an operating control system (21) to achieve the estimated heating strategy.

Abstract: An electromagnetic cooking device is disclosed. The device comprises an enclosed cavity configured to receive a food load and a plurality of amplifiers configured to amplify a first RF signal and a second RF signal thereby supplying the RF signals to the enclosed cavity. A controller is in communication with the plurality of amplifiers. The controller is configured to control the first RF signal and the second RF signal along a stirring path between a first approximate resonant mode and a second approximate resonant mode of the enclosed cavity. Each of the resonance modes comprises a frequency and phase shift between the first RF signal and the second RF signal.
