The Beta-Hyperbolic Secant Distribution
The shape of a probability distribution is often summarized by the distribution’s skewness and kurtosis. Starting from a symmetric “parent” density f on the real line, we can modify its shape (i.e. introduce skewness and in-/decrease kurtosis) if f is appropriately weighted. In particular, every density w on the interval (0, 1) is a specific weighting function. Within this work, we follow up a ...

متن کاملPlanar gradient hyperbolic secant lens for subwavelength focusing and superresolution imaging
Integral relations to describe the propagation of a TE-wave from an external point source through the two-dimensional medium (plane interface) and the plane-parallel plate are proposed. We discuss three types of waves that contribute to the resulting light field, namely, the propagating waves and the firstand second-type surface waves. The comparison of near-field refractive lenses (SIL, NAIL) ...
