Definitions

  • the subject of the invention is a device for transmitting an electromagnetic radiation to a body or substance in order to subject this to the influence oi the transmitted energy.
  • the device is especially intended to serve medical purposes, although it will be advantageous also when employed for other purposes, such as the chemical treatment of certain substances.
  • the invention therefore proposes to employ a radiation field whose transmission properties are similar to those of the object to be treated by means of the radiation.
  • the device here shown may serve for instance medical purposes, that is to say, may serve as a means for treating a human or animal body K.
  • a suitably shaped member C preferably of a ceramic material, is employed.
  • a dipole D is disposed, which is connected by an energy line E to an oscillation generator G.
  • A denotes a condenser for shortening the dipole. This arrangement may be accomplished by embedding the parts D, A when manufacturing the member C, or by forming this member with an excavation having the shape of the structure D, A, and then filling this excavation with metal or providing it with a metal coating.
  • the body K for instance consisting to a large extent of water, insulating materials whose dielectric constant is in the order of magnitude of that of the body to be treated are easy to find out among the insulating materials of high dielectric constant nowadays available. Any other suitable insulating material may of course be used, such as a non-ceramic material.
  • the shape of the member C should be such that the energy will be transmitted without having to pass through air.
  • Devices of this construction may be provided with means for energy concentration and screening, such means being well known per se.
  • member C shaped accordingly, may be fitted with a metal coating R that shall effect an energy concentration by acting as a reflector.
  • This coating may in a well known manner be applied to the ceramic member C by melting so as to provide for an intimate contact between the two and create a handy structure in this way.
  • a device for transmitting electromagnetic radiation to bodies or substances comprising an oscillation generator, a dipole from which the radiation is emitted connected to the said generator, and a dielectric filling the space between the body or substance and the dipole, the transmission properties of this dielectric being different from those of air and similar to those of the said body or substance receiving the radiation.
  • a ceramic member forming the dielectric, a dipole within this member and an energy line interconnecting this dipole and the oscillation generator.
  • a ceramic member forming the dielectric means for causing the oscillations to become effective within this member, and reflecting means, attached to the surface of the ceramic member, for concentrating the energy to be transmitted.
  • a device for transmitting electromagnetic radiation to a body or substance comprising means for radiating oscillatory energy and a dielectric filling the space between said body or substance and said means, the transmission properties of said dielectric being different from those of air and similar to those of the said body or substance.
