Abstract. In this article a new parabolic equation for wave propagation inside inhomogeneous dielectric media is presented and an algorithm of its solution is treated. That algorithm is verified using the Mikaelian and Maxwell cylindrical lenses focusing properties. The near-field and far-field calculations for the gradient and radial-layered Maxwell lens antenna are done. The design of planar radially-layered Luneberg lens with H₁₀ wave excitation is considered and comparison parabolic equation technique with a rigorous solution is produced. The presented results were reported at the III Microwave week.
