Abstract
Disclosed is a tuneable microwave apparatus useful in carrying out chemical and physical processes on a sample, particularly including polymerization. The apparatus includes a cavity in which the sample is disposed, a microwave supply, microwave power meter and sensor, means for sensing the temperature in the cavity, means for varying the volume of the chamber within the cavity wherein the sample is disposed, means for measuring microwave reflection from the sample, and computer-controlled means operatively associated with the foregoing to vary the microwave power and the size of the chamber. Openings are provided within the chamber to permit removal of vapor generated during expousre of the sample to the microwave radiation.
