Application of Slow-Wave Structures for RF and Microwave Heating
P. 18–21.
Mamontov A. V., Pchelnikov Y. N.
Wide application of radiofrequency (RF) and microwave (MW) heating of dielectric materials is restrained by the relatively small specific RF losses and inhomogeneity of the MW energy penetration in the treated objects. These disadvantages may be overcome by using applicators based on slow-wave structures which support modes in which the phase velocity is less than the free-space velocity of light These structures concentrate the electromagnetic field relatively homogeneously along the system axis. Diverse applications have been found including food heating, disinfecting agricultural products, and electro-coagulation.
