Abstract :
The electrical field strength induced in tissues depends upon the constants of the material of the radiator. The magnetic permeability increases the strength of the near field, and the conductivity decreases it. A radiator with a certain shape and certain dimensions can be composed of various materials. For various combinations of materials, different field patterns are obtained. Thus the SAR patterns can have either sharp changes or smooth variations.
