Abstract : A device for, and a method of, delivering a known amount (i.e., a dose) of electromagnetic energy radiation in the radiofrequency/microwave frequency range to a specimen of organic material (e.g. a cell and/or a tissue culture), and thereby exposing the specimen to the delivered energy. The device comprises a source of the desired electromagnetic energy to which is electrically connected a coaxial cable having an open end which terminates in a centrally located aperture of a circular brass ground plane plate to which, in turn, is electrically and mechanically connected to a metallic ring which is positioned such that it is equidistant from the aperture in which the energy-radiating open end of the coaxial cable is located. A circular culture dish which is positioned over the aperture, within the metallic ring, and on the ground plane plate holds the specimen of organic material which is exposed to the energy radiated from the open end of the coaxial cable.
