Three-dimensional vectorial analysis of an electromagnetic non-diffracting high-order Bessel trigonometric beam

► The vector wave analysis of an electromagnetic high-order Bessel trigonometric beam is presented. ► Maxwell's equations and Lorenz' gauge condition are used to derive the fields expressions. ► Computations are performed for cases where k/kR approaches to unity and largely exceeds it. ► Results demonstrate the significant differences for the fields components in those two limits. ► The results are important in the study of electromagnetic wave scattering and radiation forces.
