Chemical vapor deposition coating of fibers using microwave application
First Claim
Patent Images
1. A method of heating a plurality of fibers, comprising:
- providing said fibers in an environment which produces microwave energy that is substantially dependent only on radius within a cylindrical cavity;
observing said fibers, to determine a color thereof caused by the heating caused by the microwave;
adjusting a position of at least one of said fibers to make the color, and hence heating effect, more uniform; and
carrying out an operation on the heated fibers.

Abstract
Chemical vapor deposition coating is carried out in a cylindrical cavity. The fibers are heated by a microwave source that is uses a TM0N0 mode, where O is an integer, and produces a field that depends substantially only on radius. The fibers are observed to determine their heating, and their position can be adjusted. Once the fibers are uniformly heated, a CVD reagent is added to process the fibers.
