A method for generating a microwave vortex field

Abstract

In this paper, we propose an on-end structure of a circular waveguide that forms a vortex field of the microwave range. We construct its numerical model. The numerical experiments conducted confirm the possibility of generating a microwave vortex field by means of the proposed structure. The best suitable material for fabricating this structure is also selected in the work..
