Deep Effect and Localisation in the Short-Wave Condenser Field

Abstract

Any object introduced into the condenser field deforms it. This and the radiation of the short-wave condenser makes an exact dosage illusionary. It is shown that dielectrics or semi-conductors, like, e.g., electrolytes, body-tissue or limbs, do not deform the field indiscriminately, but refract the lines of force. With a suitable choice of the relation of the surfaces of the electrodes to the cross section of the dielectric (a glass tube with the white of an egg) and with the right relation of length to cross section, a selective heating takes place in the middle of the object on account of the additional lines of force entering along the tube. Objects the size and form of which do not correspond to these conditions can be suitably adapted by applying auxiliary electrodes. Waxparaffin mixtures or agar with certain admixtures are suitable materials. In this way an exact localisation of the heating and a considerable heating effect may be produced.
