Abstract
A method for changing a characteristic of a material is provided. The characteristic of the material is determined by the nature of the bond coupling certain molecular components in the material. The material is exposed to electromagnetic energy having a frequency range related to the bond coupling two molecular components in the material. During the time the material is exposed to the electromagnetic energy, stress is applied to the material. As a result, the bond is broken and then subsequently a different bond is formed by the simultaneous application of the stress and the electromagnetic energy. The structure of the new bond is determined in part by the stress.
