Аннотация: The method of the inhomogeneous Mikaelian lens constructing is presented and investigated. The lens is implemented as a discrete medium which is a stack of figured layers of certain geometry, similar to flower with petals. The dependence of aperture efficiency on layer thickness t and the number of the "petals" N was investigated. It was found that discontinuities of the discrete structure representing the lens can exceed the wavelength still retaining high value of aperture efficiency. It was demonstrated that numerical optimization of "petal" profile along with anisotropy accounting can significantly increase the aperture efficiency of the Mikaelian lens.
