Abstract
A method and apparatus for ultrafast microwave tissue fixation using a single mode resonant waveguide constructed with an aperture near one end. The waveguide is also constructed to provide a uniform E field and maximum power field below the aperture. Tissue is placed into a vial filled with fixation solution. The vial and tissue are then inserted through the aperture into the waveguide. Microwave energy is then applied to the tissue which becomes fixated within a short period of time.
