Characteristics of Circularly Polarized Multimode Helical Beams
In this paper, a theoretical and numerical analysis to determine the properties of circularly polarized helical beams is presented. A beam-port has been programmed to reproduce the fields radiated by a circularly polarized helical beam antenna designed at the frequency of 10GHz. The propagation of four different circularly polarized helical modes over a distance of 3 m has been studied using time-domain analysis with CFDTD and analytical models. Thanks to the great volume of the simulations, the properties of these beam have been delineated and compared with the linearly polarized helical beams. The design of the antenna and the beam-port was developed using the CFDTD method and a Titan-XP GPU.
