  • Patent number: 6191402
    Abstract: An apparatus that enables a homogenous heating and an efficient measurement of organic as well as a mixture of organic and inorganic materials. The apparatus is characterized in that a load, placed in a cavity with very small dimensions in relation to the wavelength in vacuum at applied frequency, is heated by a generated pulsating near field.

  • Patent number: 5977532
    Abstract: According to a method for the heating of dielectric materials, the heat generation is done by oscillating electromagnetic radiation of one or more frequencies within the frequency range 300 kHz-299 MHz, preferably within the frequency range 1 MHz-299 MHz and best of all within the frequency range 12 MHz-200 MHz. In an apparatus for the heating of dielectric materials, preferably of organic nature, the heat is generated by oscillating electromagnetic radiation within the frequency range 300 kHz-299 MHz. The apparatus comprises a chamber (10) consisting of an upper wall (12), a bottom wall (11) and side walls (13, 14, 15, 16) made of electric conducting materials, which walls together with at least one generator (19) are connected to a common reference potential at which the generator (19) is arranged to feed at least one with the chamber cooperating antenna (17) in order to get the electromagnetic radiation in this chamber.
