Abstract
The present disclosure relates to a microwave heating apparatus and method of heating a load using microwaves. The microwave heating apparatus comprises a cavity dividable into at least two compartments, a first microwave generator and a first feeding port for feeding a first mode field in a first compartment of the cavity, a second microwave generator and a second feeding port for feeding a second mode field in a second compartment of the cavity. The first mode field and the second mode field provide complementary heating patterns in the cavity when the cavity is undivided. The present disclosure provides the flexibility of heating a load in a large cavity or heating a plurality of loads in smaller compartments of the cavity while still providing even heating in the cavity and in the compartments.
