This contribution deals with the evaluation of effects of a cylindrical metallic cavity on the radiation of a planar longitudinally-polarized Bessel beam launcher, and it is related to applications of nondiffractive waves to microwave heating or plasma excitation. A full analytical model is developed to extract fundamental physics insight of the problem at hand. Full-wave numerical simulations by COMSOL Multiphysics have been adopted to validate the proposed model, showing fair agreement between simulations and theoretical predictions.

Abstract
This contribution deals with the evaluation of effects of a cylindrical metallic cavity on the radiation of a planar longitudinally-polarized Bessel beam launcher, and it is related to applications of nondiffractive waves to microwave heating or plasma excitation. A full analytical model is developed to extract fundamental physics insight of the problem at hand. Full-wave numerical simulations by COMSOL Multiphysics have been adopted to validate the proposed model, showing fair agreement between simulations and theoretical predictions.File in questo prodotto:
