In one embodiment, controlling the spatial distribution of an electromagnetic field in a system involves determining an inflection frequency for energy applied to the system below which a first spatial distribution results and above which a second spatial distribution results, selecting an excitation frequency to be used to generate an electromagnetic field to be applied to the system based upon the determined inflection frequency, and applying an electromagnetic field generated using the selected excitation frequency.
