Abstract

HIGH-FREQUENCY radio waves such as are used in television (3-20 m. in length), can increase the temperature of certain solutions and of living tissues, and have been used in medical practice (diathermic treatment). Dr. Franz Nagelschmidt describes a method of directing and localising the heating effect by interposing dielectric substances (wax, ebonite) between the electrodes and object, and gives suggestions for practical applications.
