Abstract

The microwave heating of a thin carbon coated ceramic fiber is modeled and analyzed in the small Biot number regime. The electric field is assumed known and uniform throughout the cross-section, and does not vary along the axis of the cylinder. We present a model which gives a functional relationship between the coating thickness and the final temperature of the fiber. It gives a plausible explanation of the experimentally observed time evolution of temperature for a tow of fibers [1].
