Abstract
Electromagnetic (EM) drying of a plugged ware is provided that includes subjecting the ware to an axially non-uniform EM radiation field that causes more EM radiation to be dissipated in either of the plugged regions than in the unplugged region. The EM radiation field is provided by a configurable applicator system that includes a feed waveguide and a conveyor path. The feed waveguide includes configurable slots. The configurable applicator system can be set to selectively vary the amount of EM radiation dissipated by each ware along the longitudinal axis of each ware as a function of ware position along the conveying path, thereby enhancing the EM drying process.
