On the Possibility of Reflectionless Propagation of Plane Acoustic Waves in Continuously Stratified Media

Abstract The example of vertical propagation acoustic plane waves in the atmosphere is used to establish that reflectionless occurs only continuously stratified media for which wave equations with variable pressure perturbation and vibrational velocity coefficients are reduced—via same transformation impedance profile, inversely proportional refractive index—to a comparison equation constant coefficients. It shown corresponding transformations possible impedance.
