Abstract

Numerical simulations were used to investigate the effectiveness for materials processing of recently announced microwave spot-heating applicators. These devices can produce heating in depth over a region a centimeter or two in diameter. Computed 3-D time-dependent temperature distributions for both stationary and moving samples suggest that such applicators could be very useful for joining of ceramics, such as alumina. Moving the beam relative to the workpiece at an appropriate rate avoids thermal runaway.
