title: Radiation pattern of azimuthally varying scalar Laguerre-Gauss waves.
abstract: The exact full-wave generalization of the azimuthally varying scalar real-argument Laguerre-Gauss beam is obtained. The radiation intensity of the resulting azimuthally varying real-argument Laguerre-Gauss wave is determined. The main characteristics of the radiation intensity pattern are discussed. The total power P(n,m) is determined, where n is the radial mode number and m is the azimuthal mode number. By the use of 1/P(n,m), the characteristics of the quality of the paraxial beam approximation to the real-argument Laguerre-Gauss wave are investigated.
