Abstract A simple and straightforward principle of modified first order principle of geometrical optics was applied for the analysis and the design of the microwave power distribution in a cavity of a microwave oven. A domestic microwave oven which had nonuniform energy distribution with 10.7% mean deviation was improved to 6.1% deviation by this simple approach. This improved domestic oven was proven to be useful as a scientific microwave oven which requires more uniform microwave field distribution inside the cavity than domestic microwave ovens. This was accomplished by minor modification of stirrer and its mounting location.
