摘      要：In this work,we introduce a kind of new structured radial grating,which is named the even-type sinusoidal amplitude radial(ETASR)*** on diffraction theory and the principle of stationary phase,a comprehensive theoretical investigation on the diffraction patterns of ETASR gratings is *** results show that novel carpet beams with beautiful optical structures and distinctive characteristics have been constructed on the basics of the ETASR *** diffraction patterns are independent of propagation distance,that is,the new carpet beams have diffraction-free propagating *** non-diffracting carpet beams are divided into two types by beam characteristics:non-diffracting integer-order and half-integer-order carpet ***,we experimentally generate these carpet beams using the ETASR ***,their particularly interesting optical morphology and features are explored through numerical simulations and experiments.
