Hz. Zhang et al., A MICROWAVE APPLICATOR USING A RECTANGULAR WAVE-GUIDE WITH 2 SYMMETRICALLY PLACED DOUBLE L-SEPTA FOR PROCESSING SHEET MATERIALS, Microwave and optical technology letters, 7(15), 1994, pp. 717-720
A microwave applicator using a rectangular waveguide with two symmetri
cally placed double L septa is proposed for processing dielectric shee
t materials. The attenuation caused by the loaded lossy dielectric she
et is obtain by the Ritz-Galerkin method combined with perturbation th
eory. The results show that a microwave applicator using the proposed
structure can process dielectric sheets with a higher loss factor and/
or larger physical dimensions. (C) 1994 John Wiley & Sons, Inc.
