ABSTRACT:
An electromagnetic illuminator for the rapid thawing of cryopreserved plasma comprises a source for electromagnetic energy and a hollow waveguide having an aperture at one end for propagating and dispersing the electromagnetic waves over a predetermined area. The hollow waveguide is loaded with a liquid dielectric material having dielectric properties substantially the same as frozen plasma. A focusing medium refracts the electromagnetic waves propagating within the waveguide to provide a substantially uniform electromagnetic field across the waveguide aperture. A flexible membrane covers the aperture of the waveguide to contain the liquid dielectric material. The container of plasma to be thawed is placed against the membrane covering the aperture, and a hollow cap assembly filled with the liquid dielectric material is translated against the side of the plasma container distal to the microwave source. The container of plasma is thawed by the uniform electromagnetic field at the aperture of the waveguide. The liquid dielectric material loading the horn and cap eliminates dielectric discontinuities and serves as a thermal damper to dissipate localized heat buildup in the plasma being thawed.
