Abstract :
This paper has set forth the principles which pertain to the elimination of frequency instability and harmonic radiation from diathermy equipment, illustrating the application of the principles with an actual model. In this way it is hoped that emphasis will have been placed on the manner of obtaining the results as well as on the principles. The problem of high frequency harmonics requires facility with high frequency techniques.
