Fast Asymptotic Method for Calculating the RCS of Artificial Dielectric Toroidal Vortices in the EHF Band

For the extremely high frequency band, the analysis of the values of radar cross section for artificial dielectric toroidal vortices is carried out. Fast asymptotic method for calculating the scattering diagram of toroidal vortices of large electrical dimensions is developed. It is shown that the radar cross section growth for toroidal vortices decelerates with increasing frequency and the average radar cross section tends to some limiting values.
