A traveling wave applicator particularly suitable for heating low loss materials is described. The applicator consists of a dielectric Cantor multilayer inserted in a single-mode rectangular metallic waveguide. Field localization phenomenon occurring in the multilayer allows high field amplitude (several times the amplitude of the incident field) to be obtained in a load placed at the center of the applicator. Design examples and numerical characterization of an applicator in WR-284 waveguide operating at 2.45 GHz are presented for cylindrical and planar loads. Results show that the proposed applicator can significantly enhance the effectiveness of the heating process.

Abstract
A traveling wave applicator particularly suitable for heating low loss materials is described. The applicator consists of a dielectric Cantor multilayer inserted in a single-mode rectangular metallic waveguide. Field localization phenomenon occurring in the multilayer allows high field amplitude (several times the amplitude of the incident field) to be obtained in a load placed at the center of the applicator. Design examples and numerical characterization of an applicator in WR-284 waveguide operating at 2.45 GHz are presented for cylindrical and planar loads. Results show that the proposed applicator can significantly enhance the effectiveness of the heating process.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
